Lowe's holds Build and Grow workshops on select Saturdays throughout the year. For the 2013 holiday season, they will be having a Train Engine Workshop on Saturday, December 14 from 10-11a.
Kids will be able to build a Train Engine complete with Rub & Smell Stickers. This craft is so cute. Unfortunately, all of the stores near me have already reached capacity. Maybe you'll have better luck where you live.
You can check for availability and register online on the Lowe's Build & Grow website.
I took my daughter to a Lowe's Build and Grow workshop last spring and she had a really great time. We would have attended again except the location near our house books up quickly so I often don't know our schedule before it fills up.
