I was getting my quilts bagged up to go to a quilt show and the quilt I was getting ready to quilt is already on the table. I forgot I had taken this picture...wish I had taken it without all the piles on top of it. If you look closely you can see where I have ran strips of blue painter's tape across the area I wanted to quilt. I removed them as I went along then ran the strips across the other direction. I think it worked real well. No marking and guessing, just follow the tape and rip it off.
I think it turned out pretty good for my first try at quilting using this method.
