Thank you for responding to my question. I created templates to rotary cut the pieces.The templates are made from 1/4" acrylic and are very accurate and square. I glued sandpaper to the back so the template doesn't slide all around. The pieces are cut well.
As for sewing 1/4" seams, that is a little tricky. Most of the seam is pretty good, probably within 1/32" of being 1/4". Occasionally I make an error. I noticed last night while sewing that the first sign of trouble comes when I press the seam. Apparently I'm stretching the corners more than the middle and it is distorting the shape.
Being new to this, I have not heard of paper piecing before yesterday, perhaps I should read into that a bit.
