Hi Heather.
I have only just noticed your post, so I hope I am not to late, and the dance is over.
The Kermit I made was for the front page of my web-site, and I just wanted a nice photo. The rainbow is made from the 7 colours, and they are held together with double sided tape, and then taped to the back wall for the photo, so it is cheating a bit
The rainbow/cloud Twisty showed is a lovely design, and anything can be put under the rainbow, (Flowers, a pot of gold, a fairy, or even a little Kermit !!!!)
It is not complicated, but there are a couple of tips that make it easier. The design is fully explained on this video tutorial by Flower Clown.
