One Block Wonder Quilts!

A “One Block Wonder” quilt derives its uniqueness by the creative use of cutting, sewing, and arranging 60° triangles together into an original masterpiece. Two people can use the same fabrics, cut the same width strips, and end up with two completely different finished designs. These quilts are like looking through a kaleidoscope; what happens to your fabric print is magic! Come into the shop and marvel at the sample.

In this 3-hour class, Twila will introduce you to the principles of One Block Wonder Quilts and lead you through all the basic steps to finish your first block. Included in the price of the class is a tutorial with Twila to finish up your One Block Wonder.

Class Sewing Supplies

  1. Any one of the four One Block Wonder books written by Maxine Rosenthal. Please read the first few chapters and glance through the rest of your book for inspiration.

  2. A “cleaned” sewing machine, in good working order, with a NEW needle

  3. “Normal” sewing supplies, i.e. thread, scissors, and flower head pins

  4. A rotary cutter with a NEW blade, and a rotary cutting ruler. (Rotary cutting mats are available in the classroom)

  5. A 60° triangle, (3 1⁄2” or larger) with or without the “point”

  6. 7, identical 24" fabric panels or 6 repeats of a fabric design. Again, it is a good idea to read the book section about selecting fabric before you purchase yours. The QSC has a section of fabric set aside for One Block Wonder quilts and a new panel arriving in Feb. called "Venice" by Robert Kaufman that will be stunning to use in a One Block Wonder.

  1. Objectives

At the end of the session, you will be able to:

  • ✓  Calibrate your sewing machine to sew scant 1⁄4 inch seams. This is critical.

  • ✓  Layer and match specific designs for all layers with pins or small stitches.

  • ✓  Cut strips according to your design selection.

  • ✓  Cut triangles from at least 1 strip.

  • ✓  Arrange each triangle set to make a hexagon.

  • ✓  Sew 3 triangles of each set together to begin the designing process.

    Sewing Machine Calibration

  1. Rotary cut 3 pieces of fabric 1 1⁄2” wide and 4” long. (Teacher will have some ready)

  2. Sew the 3 strips together with what you think is a 1⁄4” seam.

  3. Press first flat, then with seams towards the inner piece.

  4. Measure center strip. It should measure exactly 1”. If not, adjust your fabric one way or the other as to its placement under the sewing machine foot, or place masking tape on your machine to guide you.

  5. Try the sewing test again to confirm your adjustments.

  6. When successful, have a treat to celebrate.
