Left and right shoes for left and right feet, RIGHT?

Gioia can put on her own shoes, and she is also a whizz with doing up buttons thanks to Button Bear.  However, 50% of the time she doesn't put her pumps on the right feet, so to speak, which means we leave the house with little toes pointing outwards as if they have had a disagreement of sorts.  I designed shoe stickers for her a while ago but never sent them in for print, but yesterday I was once more inspired...I will re-design them as a sort of two piece puzzle.  This way she can't go wrong as Bean is gem when it comes to jigsaws.
