UHMMM -- that's a hard one to decide on a favourite book. One I use a lot is "Quilting from start to finish" by Katherine Guerrier. I also really like a brilliant magazine by Quiltmaker called 100 Blocks. Volumes one and two are published and number three is due out end of April. They are very good.
I have a few Debbie Mumm and Eleanor Burns books and I love Brenda Papadakis, Dear Jane and Dear Hannah. Also Jennifer Chiaverini Sylvia's Bridal Sampler. Oh gosh this list is getting rather long - better stop !!
