HOME DEPOT store has a free children's workshop open house the FIRST SATURDAY OF EVERY MONTH from 9am - Noon! They even give each child their own orange apron to keep. We've only done this once and of course we were like running in as they were closing, but it was super fun for my little boy! click here for their website.
When: SATURDAY, MARCH 3rd, 9am-noon
What: Just show up and make this CAR with your child for free
LOWE'S also has a children's workshop called "Build and Grow" which happens every other Saturday. But, with Lowe's you have to sign up and in my area the spots seem to fill up way to fast. Maybe your area would be easier. click here for their website. Have fun!
