I have been working on a crib quilt for several weeks. My client had already decided that she wanted horses and sketched a horse made of 1 inch squares. I took it from there. Assembling the horse block was my greatest challenge.
The hardest parts of the patchwork are the little triangles. This method of making them (called half-square triangles) is the best i have found. They remain fairly square after all is said and done. Its best to pencil in a diagonal line. It is also helpful to line up a bunch of these layered squares and sew them in a continuous row. (keeps the beginning and end from catching on the feed dogs of the machine)
Before pressing the half-square triangle open, trim off the seam allowance. Press without stretching by lowering the iron straight down on the seam. Then begin to assemble the parts. Instead of all 1 inch squares, I combined areas where I could.
