Finally got the list of fabrics she used. There is a Yahoo group for this BOM called erinsquilters. I posted that I couldn't find it after the first time and someone put up the list.

She also explains the fabric in a blog post on Sept. 15, 2010 (maybe why I couldn't find it the second time, didn't go back far enough).
