I struggled with that very thing last night! I've been staring at a stack of fabrics I had chosen to make a quilt for my grandson, this will be my second quilt. I was fine cutting the accent pieces, but when it came time to start cutting the main piece, I was scared to death! LOL! Well, once I made the first cut I was fine, and I've already realized I made some errors in measurement, but I'm still okay! I'll just adjust for it later! Just make that first cut, I'm sure it will turn out great!
