Sorry, I have been MIA, my washing machine flooded part of my house, we still don't have flooring but the fans and dehumidfiers are gone, still kind of musty smelling. I haven't started mine yet, I have figured out the design and got most of the fabric bought. The zip equals 18. I am already wanting to keep it for myself, thankfully I always buy extra fabric. I am baby quilt central over here, I have three, and possibly another to make because she may be having twins did I mention they all have to be done by June. I don't know what I got myself into!!!...
