I love the idea, and would participate. I'm a beginner at best, and some of the blocks of the month are very intimidating to me, especially anything with triangles...LOL.
So, you can count me in if you should move forward with this.
I also like your suggestion of a once a month kind of thing, because I know for me and my schedule I could devote quality time to it, and not waste your time.
Thanks for the great idea!!
