I have googled "double framed 9 patch" and have turned up nothing. The closest thing is a "Framed 9 Patch" that was put out in the 1950s. It is a 7 inch block. My mother told me that she got the pattern from the newspaper during the 1950s but she didn't know the name I suspect that my grandmother wanted a 12 inch block and added the additional frame giving the block a totally different look.
If quilting is like the apparel design world, copy right laws for designs are not strictly enforced because there are only a x-number of silhouettes in design. Also, I'm not going to commercially produce this pattern.
