Dust free sanding for drywall - Also a great tool for getting smooth drywall patches 

Do you want an easy way to make wall patches without all the dust and over sanding? Then you must check out this simple sponge.
I found this sponge at Lowe's near with the rest of they drywall supplies.
As a backup you can use a tile sponge with the rough back on it the same way. It's just a little big to handle for the wall.
