I like "That Perfect Stitch" by Roxanne McElroy and "Handquilting With Alex Anderson.
The Anderson book has great photos for all different combinations of right handed- left handed, which finger you wear your thimble on as well as thumb quilting. The McElroy book gives al ot of details and advice on technique and materials. Good luck, it takes some practice at first, but is very relaxing when you get into it!
