There seems to be an abundance of free crafts for kids to make at local retail stores. Michael's, Home Depot, and Lowe's all have workshops that kids (and adults!) can make crafts, usually for free, but sometimes for a small fee. Maybe it's the recession, or maybe it's a way to get more customers, or a combination of both - but either way, there seems to be a huge reception to these events.
Saturday, June 26th, your children can make a Monster Truck, and on Saturday, July 10th, your children can make a fun Ball and Cup Game!
There are 25 Lowe's Stores in Maryland, so you should be able to find one close to you!
