It's Saturday morning and you're wondering how to spend some quality time doing something different with the kids.   How about building a birdhouse that you can attach to your window?  On April 4, at 9:00 AM, the Lincoln Park Home Depot  is sponsering a free Kids Workshop on building a window birdhouse for children ages 4 - 12.  All of the materials needed to build a window birdhouse will be provided to each child free of cost.  Children must be accompanied by a parent or guardian. The Lincoln Park Home Depot is located at 2665 N. Halsted.   Have some fun with the kids while making something useful.
