When I was at the bead store, more on the beads later, I found this box with the cutest little glass bottles in it. I thought it would makes some great smelling bottles and bought it. I added some spices and made some holes in the plug that came with them. Then I took some pictures of the bottles to make some cards to go with it. Right now since he can see the contents it will be more of a matching activity with sent. But in the future I will add cotton balls with scents in the jars so that he will then match the smells.
