fore you sew the sq. onto your rectangle...make a mental note which part of the square you
will be keeping and which you will cut off. Sew just a scant more into the cut=off side as on'
the side you will be keeping. Then proceed as usual in trimming off the unused portion. For me
just that 1/32 nd of an inch (just a hairline) extra on your saved triangle will allow for the little
bit you usually are short. I hope what I'm saying is clear. It makes a world of difference for
me.
