More ideas from Kim
Definitely an awesome idea!  @Shawna Apps -- for the playroom?  And @Jennifer Pike -- wait until you see just how many Legos Jeremy has in the attic!  :)

A lego wall. Add this to my fun wall ideas. So one wall will have chalkboard paint, another dry erase, now a lego wall. Now I just need a felt wall for felt play and a magnetic wall. I saw this neat project somewhere about a ball track on a magnet wall.
