Thats what happened to me the first time i tried to sew patches in straight rows. No matter how hard you try, the size always gets a little distortion. It will work out fine Henry, just next time, instead of sewing in rows, sew your patches into 9 or 12 patch blocks, square each big block off, then sew the big blocks together in rows. I didnt know that til i saw it on a tv show. But this will work out fine, just put a pretty border on it, looks beautiful.
