I have a daughter who makes the most beautiful quilts you hae ever seen. She sews the seams and then measures each one to make sure that it is exactly 1/4 inch. Every corner matches perfectly.
I told her that I would quit quilting if I had to go to all of the trouble. I try to do a good job, to the best of my ability. If I am happy then the person receiving the quilt should be happy when I give it to them. If not then they can give it away to some one who needs a nice quilt.
I don't have enough time to be that picky. My daughter is exactly like my mother in her perfection. I think it is great, but not for me.
