Boy do I feel dumb! I couldn't figure out what the 'BQ' stood for. I looked and looked on the website and still didn't see what the BQ stood for. Then it hit me that I had been reading Big Quilts over and over and didn't see the connection. My only excuse is that I haven't finished my first cup of coffee yet. I had better drink faster.
Your picture does certainly look like the BQ series. However, I have to say that I like your picture the best in all of the series. It is very colorful and seems that it would be easy to do and easy to make up your own pattern.
If you do find the pattern, let us know. Thanks.
