I wanted to take this set of 2 so you can bend an adult clothing side (with blue) and those of children (yellow). In the end my 4 year old daughter was monopolized yellow and fold clothes happy sisters .. I help out setting up the machine- suddenly, when she helps me, it takes more time - but we have fun when she bends, saying "left, right, middle, I put left middle right, I put, .. ". I think that this pleasure will not last (such as wanting to vacuum), but until the clothes are neat stacks!
