Skip triangle math with strips: try Twosey Foursey

If you’ve been around the quilt block a few times, you know about mathematical formulas for figuring seam allowances. They go like this:

Seam allowances for quilts with triangles

The more you cut, the more math you have to do. It can get downright complicated!

Author Cathy Wierzbicki isn’t a fan of mind-numbing math. She’s such an anti-fan, in fact, that she wrote an entire quilt book about skipping that kind of math altogether. In Twosey-Foursey Quilts you’ll need to remember only two numbers: 2½" and 4½".

The two numbers refer to fabric-strip widths. And in 20 versatile quilt patterns, you’ll learn to cut every shape you need—triangles included—from those two sizes of strips.

Choose from three different ways to turn your fabric strips into beautiful quilts:

1. Use the All-in-One Ruler (Cathy’s preferred method), an all-purpose ruler that will help you simplify any quilt pattern.

2. Make templates that duplicate what the All-in-One Ruler does. (You’ll need only two templates to make all 20 quilts.)

3. Go with traditional rotary-cutting formulas. (Charts are included if you are so inclined!)

Once you choose a method, you can make a variety of quilts featuring half-square and quarter-square triangles, all made easier with Cathy’s strip-savvy techniques.

  • Pupil – advanced pupil in hand piecing. struggling with basting, learning machine piecing. Have to get pass basting class to move into quilting.

  • Preschooler. It is great that a ruler can do all the math and I would just have to follow the lines.

  • Sad to say that I fall into the pre-school group, but I do manage to get the job done,I just don’t give up easy!

  • I have three of Cathy’s books. Started in 2007 when we made a raffle quilt from Coffee-Time Quilts in red, then again in 2011 when our guild again made that quilt in blue. Both very successful raffles.

    I purchased Twosey-Foursey Quilts in 2008 and after the first quilt, purchased the All-in-One Ruler, a tremendous help. To date I have made Beginner’s Delight (3) and Feathered Foursome (l). Cathy’s books are easy to follow and extremely accurate. Geometric Gems is still in my "to do" pile along with several dozen other quilts I am still hoping to make. You keep making my pile grow with your great selections.

  • Definitely preschool. I hate math. I despise the fact that it enters into quiltmaking which ruins the fun. I don’t have one quilt that is square. But, they are loved anyway. This book could help me–MAYBE.

  • I would say pupil…I don’t mind the math, but don’t like cutting the 7/8″
    ones. I love this concept and this book!! First time I’ve seen one ruler do it all!! Wonderful.

  • I am a pupil.

  • Looks like a win/win deal to me as math has always destroyed my serenity.

    Donna on October 18, 2014
  • I’m a math teacher so math doesn’t phase me. I don’t understand how to quilt without math, especially geometry so I admire anyone who’s innovative enough to come up with methods that skip the math.

    —Kathy Renz on October 18, 2014
  • I’m a "Professor" and have the hard copy of the Twosey Fourseys book by Kathy. I also have the all-in-one ruler, but in my very beginnings I hated the 7/8″ concept and often used a whole number instead and cut it down my square upon completion. Kathy made life simplier for me and I greatly appreciate her.

    The Splash Dance and Prairie Stars are my two favorite patterns.

    Keep smiling,

  • Please tell me where to find the patter for Thequilt/table topper at the right top of the Stitch This header. It is the large appliqué flower on a beige background with the black and white squares. I believe it is a Kim Diehl pattern but can’t find it.

    thanks for your help. Judy

    Hi Judy, that pattern is in Urban Country Quilts by Jeanne Large and Shelley Wicks. Thanks for your comment!
