Here is a design I haven't even thought about in years. I've been making Rainbow hats, or rainbows with pots of gold as their base... I've forgotten about the simple rainbow in the clouds.
Here is my quickest version of a rainbow. I know some twisters may not want to use as many colors as I did. I happened to have all the colors in a rainbow except indigo, so I used all that I had.
See you tomorrow.
