I have to say my most favorite of all was the 'series' we did in year 3.
And, I will go back to making more 'Moons'.
I commented on Cynthia's query about using the Challenge as a study or a skill enhancing effort. If we were to do something like that... how about with an end view goal in mind... such as for the August challenge, we each make something using the 'benefits' of the years challenges in, say, a predetermined size.. which we would then put up in show form like the QA15?
Is that too ambitious?
