Colour Balancing Game

 Buying a box is to impersonal. So I decided to make my niece and nephew a twister mat. (Don't tell Hasbro.) The fabric is from second hand pillow cases and sheets. And it is backed with some non slip plastic so it won't move on the timber floor.
There were some issues with the machine in the last minute rush before Christmas. It stop working for I while and I thought I might have to buy the box after all.
I'm told it has been much used already.
