DIY Fall Chalkboard. Great for the holidays. Make a large one for the kitchen, and small ones to place around the table for thanksgiving as place cards. Could even use the small ones for labeling food dishes on the buffet table.
"Use a white light switch cover and decorate your own with sharpies!" Look, I tried decorating something with horizontal Sharpie patterns and it did NOT look like this. Also, do you really want to buy all those colored Sharpies?
