Flashback Friday

Who know I would have trouble finding an old school chalkboard eraser?  I wanted to get one to use on the cool chalkboard-painted-wall in the new coffee shop at church, and I never dreamed I would have this much trouble.  I finally found on at Staples.  But even then it's not a plain ole old school eraser - it's a fancy one, for chalkboards and for dry erase boards.  I bought it, reluctantly, just because it was the only one I could find.
