Myself?? Not a single one has been made with no "do-overs." To me that's just a given...I will have to get out the seam ripper and spend some time going backwards. I, however, have seen some that I do believe have been put together in one fell swoop, but pretty much show that being concerned about one block being the same size as the next, or one fabrict doesn't go with the plan just isn't a big problem for the maker of the quilt. In some ways I almost have to admire those who aren't as picky as I am. I have a very good friend who just laughs it off when she makes an error. She can also make probably three quilts to my one.
