I enjoy making log cabin quilts and wanted to see what this book offers, so I found this link:

These would definitely be more complex than regular log cabin quilts, and it is potentially more difficult to collaborate on a quilt. Especially with these types of patterns, I think collaboration would be difficult as there is so much chance of slight variations in cuts (different rulers?), slight variations in sewn seam allowances, and even perhaps differences in stretching of the bias edges. If I were going to make one of these quilts, I would want to do it all myself!
