An all-in-one ruler for quilters? It exists!

Rotary rulers. How many do you own? It seems like there’s a different ruler out there for every cutting task. But did you know there’s one ruler designed to do the job of many? It proudly proclaims its mission in its name: the All-in-One Ruler™.

All-in-One Ruler
The ruler measures 6″ x 18″—no bigger than many rectangular rotary rulers.

The All-in-One Ruler helps you cut basic squares, rectangles, and strips, of course. But because of the diagonal slant on the right and the special markings on the back, it may be the only ruler you’ll ever need.

Things start to get exciting when you learn how the ruler helps with cutting triangles. Instead of cutting squares from yardage, and then cross-cutting those squares into triangles, the ruler helps you easily cut triangles from strips of fabric. See here:

Cutting half-square triangles from strips
Cutting half-square triangles from strips. The ruler makes diagonal cutting a snap. Position the ruler on top of the strip as shown (above left) and cut along the diagonal edge. To cut the next triangle, rotate and flip the ruler to the right (above right) and cut along the right edge of the ruler. For this second cut, the back side of the ruler is facing up. The ruler is marked with reverse printing, making the numbers easy to read from both sides.

Cutting quarter-square triangles from strips
Cutting quarter-square triangles from strips. Printed diagonal lines show what strip size to use to arrive at a desired finished size. To cut, align the notched corner of the ruler with the top edge of the fabric strip; then cut along both edges of the ruler (above left). To cut the next quarter-square triangle, rotate the ruler, align the left edge with the previous cut, and cut along the right edge (above right).

Here are a few of the quilts that Cathy Wierzbicki, inventor of the All-in-One Ruler, designed using this handy tool. Each design starts with nothing but strips! Find all of these patterns and more in Cathy’s eBook Twosey-Foursey Quilts.

Point trimmerOf all the things the All-in-One Ruler can do, trimming triangle points could be its best benefit. The blunt-edge trimmer lets you cut the points off triangles before you sew—and that’s the key to consistent accuracy, enabling you to match up triangles perfectly. Plus, no dog ears on your patchwork!

Here’s Cathy demonstrating the ruler in action:

  • The best quilting tool that I have ever used is the Bendable LED Light
    that attaches to the sewing machine. It pinpoints a light source right
    on the presser foot. With the eyesight condition I have, I would not be
    able to quilt/sew as much as I do. I have one on each of my 3 machines.

  • My number one quilting gadget is my marking pen! I mark everything!

    —Lana Bell on July 9, 2014
  • Is this ruler a non slip ruler? Then it would be perfect!

    Hi Angela,
    Sorry, the ruler is not "non-slip".

  • My rotary cutter and ruler – that’s two, but they’re a unit!

    —Pat on July 9, 2014
  • June Tailor rulers that have the slots to make cutting strips fast and easy.

    —Deb Johnson on July 9, 2014
  • My "have bag will travel" that holds my most important tools I use, i.e. rulers of various types & sizes, rotary cutter, marking pencils/pens, seam ripper, etc. It is made of a Mary Engelbrit sewing pattern and so bright, cheerful and easy to locate when I am off to do a project.

    —Betty Paschal on July 9, 2014
  • My number one gadget is my "sidewinder" portable bobbin winder . Also, I couldn’t live without my steam generator iron.

    Lu Lane on July 9, 2014
  • My Fons and Porter chalk marking mechanical pencil is great for marking on dark fabrics. They can be seen and easily rub off when you no longer need them.

    —Alvina Nelson on July 9, 2014
  • My favorite #1 quilting tool is the scapulae type seam ripper. It is extremely sharp and so precise you can pick one thread with ease.

    —connie b on July 9, 2014
  • Other that my machine and iron I really love my spray starch. I didn’t use it until the last few quilts. Oh what a difference it makes. Next of course would be my rulers.

    —Tina on July 9, 2014
  • I cannot live without my rotary cutter and mat. I cut all my pieces for my quilting.

    —beth daniels on July 9, 2014
  • Believe it or not, my favorite tool is Microsoft Word. I can scan, draw, resize, use non-square trianges and wedges, whereever my imagination takes me. And then print my pattern for paper piecing or applique.

    —Lynne on July 9, 2014
  • The Ruler looks like it will save a lot of time cutting fabric. I have a question, can all Rotary cutter be used with the ruler? Hellene

    Yes, Hellene, any standard rotary cutter can be used with the ruler. Thanks for your question! –Jenny

    —Hellene R. Moore on July 9, 2014
  • Well, though not a gadget – my machinger gloves are with me always – when I need the little extra grip – or protection for my hands or fabric. When you purchase a snug fitting size – they are like no gloves at all!!!

    —Jane from MA on July 9, 2014
  • My sewing machine. Its not top of the line, but has some decorative stitches. I can & do occasionally hand piece/applique, but I love using a machine. I can get so much more done & have really enjoyed sewing on one since I was pretty young.

    —Sharon G on July 9, 2014
  • The All-in-one-Ruler is very nice. Hellene

    —Hellene R. Moore on July 9, 2014
  • My fabric calculator. Does all the calculating for me to tell me how much fabric I need for a block or quilt, to what size to cut things for various shapes, etc.

    —Phyllis on July 9, 2014
  • my seam ripper of course!

    —Sherida on July 9, 2014
  • I love my Clover chaco wheel liner. I fill it with Hancy’s iron-off pounce powder and can make fine lines that will stay until I no longer need them.

    —Sandy on July 9, 2014
  • Rotary cutter!

    —Cindy on July 9, 2014
  • I could not live without my quilting gloves. What a huge difference they make when I am trying to machine quilt a queen size quilt.

    —Cathie on July 9, 2014
  • It would have to be a seam ripper. Can’t think of a more used tool in my sewing room.

    —Chris on July 9, 2014
  • I really appreciate my stiletto and seam ripper ~ both help a bunch!

    —Jo Stovall on July 10, 2014
  • Wow! I was looking for one of my rulers, and discovered I have this ruler a friend gave toe me…now I’m going to start using it!!!
    I just can’t live without a ruler! It really crisps up a quilt block when it’s measured correctly! With this ruler and my rotary cutter I’m on my way to a nice quilt block and great looking quilt when finished!

    —Jeanette Spellmeyer on July 10, 2014
  • A small hook crochet hook, I use it to tie knots, clean out iron holes, grab thread at the sewing machine needle, and so many other things.

    —Quilting Tangent on July 10, 2014
  • I can’t live without my oval and round nested cookie cutters. I’ve used them so much with my fabric postcards that I’ve paid them off. The are both design tools and templates.

    —Ocotilla on July 11, 2014
  • My favorite tool is my walking foot.

    —Kathleen Gold on July 11, 2014
  • Wow! There are "favorite gadgets" listed here that I’ve either never heard of or never considered using in my projects. I need to spend more time at my favorite quilting shops or in guild meetings. My favorite unsung hero gadget would be my cutting mat(s)…without them my rotary cutters and rulers wouldn’t be very helpful. In addition, my cutting mat defines my work space on the table. Don’t anyone set their books, or the newspaper or the mail or anything else in that space!

    —Pearl on July 11, 2014
  • I love my "Purple Thang"—a simple purple stylus that’s great for poking the screen on my machine, easing thread around the presser foot or turning corners. A little 1/4-inch square at one end is invaluable for checking quilt seams. I keep it on a purple ribbon so it’s always easy to find.

    Fran Gardner on July 11, 2014
  • My Elmer’s washable glue stick seems to have become my favorite tool lately, doing small intricate pieces for a BOM.

    —Donna on July 11, 2014
  • The All-in-one ruler is nice, but unless it has the sandpaper backing like Creative Grids Rulers, it would be difficult for me to use with my shaky hands.

    My favorite gadget…my cutting mat; it is the foundation for all the creativity to follow.

    Keep smiling,

    Lynnita Shipman on July 11, 2014
  • My rotary cutter!

    —Mary on July 11, 2014
  • My favorite gadget is my rotary cutter and mat. They have saved me so much time cutting things that I sew and the accuracy is so much better.

    —Louise Buker on July 11, 2014
  • The rotary cutter. My hand strength is not what it used to be, and it is a lot easier to use the rotary cutter than a scissors. Of course that means I need a ruler and a mat to go with it.☺

    —Nancy on July 12, 2014
  • I would definitely say the pad and pen set that sits by my favorite chair that I sit in to do hand work? Why? Because that is where I keep my "WANT" list that my family goes to when they want to buy me a present. Always quilting items! How did they know ? Lol!

    —Missy on July 12, 2014
  • My 2 1/2 in wide ruler! I use it in practically every pattern that I make? I love the green lines as they are easier to see at night when my eyes are tired.

    —Katy L on July 14, 2014
  • The gadget I must have are super sharp scissors. Another would be my
    1/2 inch ruler so that I can put it on a line and mark 1/4″or either side of the line.

    —Robin R Klein on July 14, 2014
  • My quarter inch presser foot with guide! Love it!!!

    —Maureen DeLassus on July 15, 2014
  • I love my rotating cutting mat and rotary cutter, it makes it so much easier to cut your pieces out.

    —Sharilyn on July 15, 2014
  • Have to say rotary cutter and ruler.

    —Linda Evans on July 15, 2014
  • Essa régua é vendida e despachada para o Brasil ? Quanto custa ? Pode ser pago como ? (Translation: This ruler is sold and shipped to Brazil? How much? Can be paid as?)

    Hi Tânia, yes, the ruler can be shipped to Brazil. To find out shipping costs, please put the ruler in your shopping cart and proceed to checkout. When you input your address and choose a shipping method, the cost will show up. Thanks for your question! –Jenny

    —Tânia Chinaglia Poli on July 16, 2014
  • Rotary cutter. Have to have it!

    —Susan Stanton on July 18, 2014
  • Rotary cutters are such a great tool to have in the crafts arsenal…with a new sharp blade of course!

    —ruby t on July 18, 2014
  • My mom use to tell me you are only as good as your tools. I think the All In One would be a great addition to my tool collection. So far I can’t pick a favorite tool. Every tool that was mentioned I agreed would make a good favorite one.

    Cheryl on July 19, 2014
  • I have been trying to find an ALL-In-One ruler to purchase for over a year now. If you know where I can find and purchase one, PLEASE let me know.

    Hi Carolyn, I talked with our customer-service department and they suggest trying your local quilt shop or Amazon – we are no longer producing the ruler. I’m sorry for the trouble – good luck with your search! –Jenny
