Birthday presents

My project for this week is to finish making/buying P's birthday presents.  So far I've made a couple of items of clothing for her, and I'm going to make a little fishing game (if I can source some magnets).  But the big present idea is a sandpit.  However, this requires getting DH on board, and he's more than a little skeptical of the whole idea.  I think something easy with little assembly required is going to be the order of the day.
