LOVE your turtle quilt (off topic, but couldn't help exclaiming on your lovely work).
On topic: I had the privilege of hearing an internationally renown quilter speaking last night at a meeting of our local quilting guild. She said she never finished a quilt (and hers have graced the covers of magazines and hang in the national quilt museum) without wishing she had done something differently--this panel was too light, it should have been smaller/larger, I should/shouldn't have had used yellow, why on earth did I use turquoise.....She said it with a smile but we all know what she's talking about. In that spirit, I think most of us would appreciate any constructive observations that help us grow and develop as quilters.
