I tried to read all of the other responses, so I hope I'm not repeating something that has already been said. I learned to sew clothing first -- 5/8" seam. Then I took up quilting in the dark ages when everything was drawn by pencil onto fabric and cut with scissors. We used 1/2" seams. When I restarted quilting seriously a few years back, I was amazed to learn about 1/4" seams -- and that they hold! Your work is beautiful. That's what counts.
