I'm working on a quilt, "Four-Patch Plaid" from "Nickel Quilts" by Pat Speth and Charlene Thode. I thought I would show to the super easy way they have you make four-patch blocks.
First you start out with two 5 inch blocks:
Place them right sides together and sew a 1/4 inch seam on two sides.
Cut the square in half, using the stitching side to the outside.
Then press open to the darker fabric. Using 2 different halves, pin together butting the seams together.
I like to pin.:-)
After you have sewed the pinned edges, cut in half again.
You have 2 four-patch blocks made! Love how easy this is. And it works great as a "Leader and Ender."
