I recently made this chalkboard banner. It combines the versitility of a chalkboard with a banner. You can erase it and rewrite something new.
Here are instructions for making it:
I found these Chipboard book kits at Michaels. I believe it was in the $ bin. Any chipboard or wood shape will work.
Paint the boards with chalkboard paint.
Once the paint is dry, I "seasoned" each board with chalk. I've always heard that you should do this on a brand new chalkboard so the first thing you write on the board doesn't make a permanent mark.
Rub each chalkboard with some chalk and then erase.
I found this chalk marker. It writes like a paint pen but when it dries it looks like chalk. It can be erased. It is not as dusty as regular chalk.
Write your letters.
Thread a ribbon through the holes on the top of the banner for hanging.
Use and re-use again and again!
