Yes the templates in the book are the right size. I only bought 5 yards of background fabric but I guess I will have to get 2 more. It is a batik and will be really hard to buy elsewhere. I looked thru the book and at least half of the blocks take just 4 3/4 X 4 3/4 squares and 3 3/4 X 3 3/4 squares. It doesn't seem to add up to that much. I love my background fabric so I guess I will have to buy more. Carol Doak said it adds up to about 5 yards but buy 7 to be safe.
