Fons & Potter has a book out on Log Cabin quilts. I have to say, I've never made a LOG CABIN quilt! But after looking through the book, I can now see that I may need to dig out my solids. I love the look of this quilt below, featured in the book!
This is and Amish Barn Raising quilt dated Feb 18th, 1921... Doesn't it look MODERN?
The book has a load of great tips on cutting your fabrics and for which size of blocks your working with so all your math is done for you. Gotta love that!
It also shows how mixing your colors can easily change the pattern and design of the quilt. Like, making the courthouse steps and other designs.
