It seems, Accu-Quilt has a barn somewhere around Omaha on which they paint a quilt. They get the design from subscribers to their site. A contest is held for the choosing and the winning designer gets some nice prizes.
jayardi, I was a tad confused but you know that's my normal state. I wasn't sure if they wanted 'a' block or a 'composition of blocks' that equaled the sizes they specified. I just sent an 18" block pattern. It looks as if yours was done the same way.
Interesting that you mentioned some of the blocks being familiar. They may have been a known block where someone just changed something in it...that does make it theirs. Right? I know yours is original, and I know mine was and that's what counts.
