Before buying anything, go see what your local library has to offer, check them out. Then buy one if it helps you and is easy to understand. Flexcoat has a book for $5 and Gudebrod has one for $6 for a couple of inexpensive ideas for starters. Take 20%off at Hook/hackle. I haven't looked at either of these two. I have Kirkmans, Garcias and Morris' books. All are helpful, but they cost more. Allyn
