I recently did the same thing, but on more than one block DUHHHH!!!! Fortunately when I realized what I had done and tht it was on every other block, I continued in that fashion and decided that it made the quilt more versatle (sp??). In other words, there was no top or bottom and I can enjoy the quilting from any direction. Delusional? Maybe, but I didn't have to rip out my quilting stitches. :-)
