FWL I would love to see more pics of your avatar quilt. I think I saw that fabric in a QS in Holland a while back - wish I'd got some now!
I can't add to what Katrine said (SHE taught me!) except to say that I do meanders in the main body, sometimes I go 'swirly' round a particular block to emphasise it. In my Turning Over a New Leaf one I posted recently, I did FMQ leafy shapes in a variegated thread but you have to look close to see it. As for the border treatments - see Katrine's! I can't come anywhere close! :D
