Bonnie's site is great with a wealth of information about so many things. I first saw it about 10 years ago when I was making Dear Jane. Glad you found it and shared it.
Quiltville is a great site. Bonnie is down home and must sew faster than anyone I know. I have made several of her patterns. I check her blog every day.
I am sitting browsing quilting websites and found a really good one called ' Quiltville' http://quiltville.com/ There is loads of stuff on there to read, and lots of photographs of amazing quilts x
