Where to begin: supplies

supply-shot

  • Laundry Basket Quilts Half Square Triangle Exchange Paper (available at your local quilt shop or at LaundryBasketQuilts.com)
  • Cotton thread (Edyta prefers Aurifil™ 2370 for color because it blends beautifully with any fabric)
  • An acrylic ruler, rotary cutter, cutting mat, pins, and desired amount of light and dark fabrics (refer to your pattern instructions for quantity)

Instructions

light-dark-layer-final

1. Cut a 6-1/2″ x 21″ rectangle from each of the light and dark fabric pieces. Place the light fabric rectangle on the dark fabric rectangle, right sides together. break

light-dark-layer-final-2 2. Lay the Triangle Exchange Paper, with printed lines facing up, on top of the light fabric piece. Each sheet of Triangle Exchange Paper will make 28 half-square triangles. Here’s a Tip: The half-square triangle’s seam allowance will automatically go toward the dark fabric when the exchange paper is placed on the light fabric. break
hopsotch-pin 3. Pin the paper in place using a hopscotch pattern—two pins in the outside triangle markings and one pin in the center. Do not pin over the dashed lines. You will be sewing on these lines. Here’s a Tip: Use a sharp 80/12 needle and cotton thread in your sewing machine and sew with a close stitch. I usually set my machine stitch to 1.5. A closer stitch allows the paper to tear away more easily.

Sew until you reach the end of the first continuous dashed line. Here’s a Tip: Use the needle down function on your machine while sewing through the paper and fabric. It will allow you to turn the corners without shifting the paper and fabric.

sewing-on-paper 5. Turn the paper and fabric and follow the arrow to sew the remaining dashed line. Remove the pins.

Here’s a Tip: If you are exchanging the half-square triangles with friends or through your quilt shop, skip the following steps and do not remove the paper or press the triangles open. It makes a fun surprise for the exchange participants to open the triangles they have received.

finger-press 7. With the paper still attached, press the half-square triangle blocks open. The seam allowance should go toward the darker fabric. Trim the “bunny ears” from the block.

finger-thumb-tear 8. Perforate the Triangle Exchange Paper by pinching the center of the light fabric triangle and the paper.
