A stone can be surprisingly stylish. It becomes a useful accent when you add felt to keep it from scratching the floor.
Tools and Materials
Gray or brown felt
Stone (at least 5 pounds)
Craft glue
The How-To
Cut felt to size and shape to fit bottom of stone.
Glue felt to stone, and let dry.

If you give this doorstop for a birthday gift, don't forget to include a homemade card that says, "At least you're not as old as this rock!"
When our daughters were young, we did a lot of camping and fishing. I usually took along paint, glue and craft supplies so we could paint rocks, pieces of wood etc. and added moss or other natural stuff. We used them as napkin holders, place cards, door stops or just sitting around. Treasured memories!
Yes, it seems obvious, but how many of us have really done it.... added felt to the bottom of a beautiful stone? Not all that many, I suppose. Martha's done it again!
This seems a bit too obvious--so simple even a caveman can do it!
I have several rock doorstops that my children painted when they were little. They are grown and on their own now, but the rocks are delightful rememberances of when they were young.
