Thanks for all of your encouragement and a touch of reason (from Ms. Betty Ninja). My decision on whether to begin yet another project is still a bit wishy-washy. I'm going to try to make some real progress on Sean's quilt before I get serious about the Civil War quilt. But I may buy the book and begin contemplating putting it together...pick out some fabrics, some easy blocks to start with, etc.
The stack of fabric above is from Purl Soho and is for the Dear Jane quilt. A few of these look perfect for the Civil War quilt as well...see, I'm starting already!
