Welcome back, Judebug. I like your horse piece. Size?
Regarding your comments about the track of this thread. In my experience, message board discussions are just that...discussions. They ebb and flow like any conversation, often going far astray of the original poster's 'intent'. Attempts to rein them in usually result in killing them.
No one has made any attempt to set up 'category' threads and I doubt anyone will. I feel those too, would wander all over the place and the result would be a half dozen general threads covering all aspects of art quilting...probably very confusing, and somewhat discouraging, to those just starting out while too much work to follow for the rest of us.
There is a great deal of technique discussion on the Challenge thread and a strong advantage of that thread over this, is that it never leaves the first page. That said, there's no reason at all that the two cannot co-exist happily.
