I strongly recommend all of them. LOL
Any quilting book that you can get your hands on will be good to have because your tastes will go back and forth through the years. But, NEVER pay full price unless you absolutely have to. I did last year in Paducah, Ky at the National Quilt Show and had Eleanor Burns sign them for me. That was a special treat for myself. Usually I look for them in thrift shops, auctions, estate sales, garage sales, Craigslist, Amazon.comm or ebay. Or if I have a 40% off coupon. Bargellos are far easier than they look. I got Bella Bella as a gift by I haven't tackled any of the mosaic quilts in it yet. You should always have a "challenge" book that you can look at and say, One of these days. . . . .
