Well, it turned out that painting the quilt wasn't quite as scary or drastic as it sounded. I wasn't entirely happy with the way the quilt was turning out - part of the 'background' was too dominant; quite distracting.
I bought 'The Painted Quilt' by Laura and Linda Kemshall quite some time ago, and have been quite taken by their use of paint in their quilts. So I figured this quilt was the one to try it on. Unfortunately I can't show you the whole quilt yet - I'll do that when I can. Suffice it to say that, while others looked at it and liked it, I know that 'letting a quilt go' (to exhibitions etc) when I am not entirely satisfied would bug me for a long time.
So I painted. Not much, just enough to mute part of the background.
