Tips for Triangles
It's easy to end up with half-square or quarter-square triangles that are too small. To avoid this, cut the triangles or squares slightly larger than you actually need. Sew the triangles together to make your square patch, then press and trim your finished patch to the size you need. Remember to leave a 1/4" seam allowance. Also, check your quarter inch seam allowance measurement, to be sure it is accurate. If it is, then sew a scant 1/4" seam. Sometimes just the fold of the fabric when you press the seam allowance to one side will make a difference in the finished size of the patch. And speaking of pressing, make sure that you are pressing -- laying your iron down on the patch, then picking the iron up, and not sliding the iron across the patch, blocks or quilt top. Sliding the iron can cause the fabric to stretch. Also, steam can cause a patch to get distorted. Try ironing with a dry iron.
