I am presently making the worse baby quilt ever. If anything could go wrong, it did. I had to take the whole thing apart. I remembered seeing this ripper at the Shop near me. I bought one and had the whole quilt apart in a very short time. I was able to then retrim my blocks and resew the whole shebang. I just finished quilting a grid on it. Even THAT has errors!!! So glad it is almost done. I like the ripper! My 7 yr old DGS wanted a hair cut!
