If you live near a beach you can easily find a lot of driftwood pieces during your walks. From them you can make a bunch of cool things like candle holders, coat racks, key holders and so on. Here is for example a wreath made of small driftwood pieces. It looks rustic and such small pieces are really easy to find. Of course the same idea will work with tree branches, dried grapevine, small scraps of wood, and many other things but only driftwood has so natura rustic look.
The whole idea is to glue together enough pieces to form a circle. Hot glue works like a charm here. You can hang such wreath on a wall in some of your rooms, on your front door or even use it like a centerpiece.
