I guess one of the worst I can think of was the king sized log cabin I made for my dad's bday/Father'sday in 1991. Mother had just passed away in fall of 1990 and I wanted to give him a little lift. I had mad several quillows, and a quilt top, but never a big quilt. I did fine on getting it sewn together and the borders and backing on. I decided to stitch in the ditch, no idea at that time about fm. I also had no idea where I needed to start my quilting-- Well guess what - I started on one side and worked to the other side, and had all but about two rows completed I'm talking about the entire quilt being done, when I realized it was really going to have a big fold in it at the edge. I asked a good quilter friend why this was happening and she laughing ask if I started in the center- "well no, why should I". I ended up ripping or unsewing the entire quilt. It took me almost a week. But I immediately learned to start from the center and go out in all directions. Now I can really laugh at myself, but then I was just furious. I have made plenty of others, we won't get into at this time.
