I'm an experienced quilter, and teach new quilters, so I'm always on the lookout for a book I can confidently recommend. The patterns are easy to follow, but unless you know what you are doing, you're going to run into trouble. So far, I've only tried the Garden Trellis pattern. I followed the instructions to sew the tube, and came to the point where I had to cut the triangles. The instructions were very explicit on lining the template up on the seams, but did not point out that the triangle template needed to be lined up 1/4" down the tube, not at the end or your blocks would come out too small....something I should have known to do, but totally missed it my first time around. Also something a beginner would have no clue about.
None of the patterns give fabric requirements for backing fabric. Unless you know how to calculate the yardage for the backing, and how to piece a backing, a beginner will be extremely frustrated. Backing is totally missing from the General Techniques section in the back of the book.
My recommendation.....Go for it! ....but be very mindful of the minute details, and DON'T FORGET TO BUY THE BACKING!!!
