Again, I really like the banners. I'm especially partial to the idea of setting up a banner on our old picnic table (probably set up for food or gifts) and maybe something near the front door or in the living room/playroom area? Or across the living room window? The nursery thing doesn't apply.
Look for a heavy paper or vinyl pull-down version meant for classrooms, as those usually have a rolling mechanism already in place. (Search "school maps" on eBay.) DIY Steps: 1. Screw brackets made for roller shades (at hardware stores) into your window frame, then mount. 2. If your map doesn't have the rods and spring attached, use a roller shade kit (find one at joann.com).
