I don't do challenges - my brain freezes at the mere thought.
One of my Guilds has one every year. One stipulation is that it must be an original design; another has something to do with fabric.
I've always loved seeing the resultant work - they're so inventive and beautiful. I don't recall that we vote on anything, just admire them. I may be misremembering this.
Is misremembering a word?
