I found this pattern Here a little while ago and finally made it the other day. I decided to make it like the colour wheel, I thought it would be helpful in teaching Ruby colours. She really loved it so I think it will be hers to use and play with.
I love how bright and colourful it is, and it is a nice little size. I made the smallest one, but there are 2 sizes to make in the pattern.
Here is the back and the edging of it. It is a nice little cushion on both sides.
