Homemade Playdough. I have made my own playdough and saw this wonderful blog post. I decided to forgo blogging about making play dough because she did such a good job and took step by step pictures. This stuff holds up really well. I actually store mine in the fridge. I personally loath Playdoh since the odor makes me nauseous. Great activity for your little ones.
