The template set contains all the templates you need to make 3 of the quilts in the book Double Wedding Ring Quilts: Traditions Made Modern by Victoria Findlay Wolfe.
in the picture you see the protecting paper still on the templates, so can see them more clearly. Remove the paper before use: the templates are transparent. There are four pieces in the set: the diamond shapes center, the small 'melon', the wide arc and a half diamond for the side. The block you make with this set will be approximately 30 x 30 inch.
