Magnetic Board... "Don't ask for "Sheet Metal" because that is super expensive...some were $40 a sheet. Go to the metal chimney or roof venting section. The pieces came in 2 sizes. This one was the largest 24" x 36" and they were only $5.00 and $7.00 each."
$12 Oil Drip Pan from Wally World - instant magnetic (large) surface. For magnetic play, displaying artwork, etc. This would be GREAT for all that magnetic poetry she wants to get her hands on. (Could try spray painting it to make it "pretty".)
