Am I the only one who thinks twigs and branches are just as attractive as flowers? Hubs and the dog and I were out for a walk this past week when I noticed this beautiful branch lying by the path. There's just something about smooth, nicely-shaped branches that I find sort of architecturally satisfying. I scooped it up, took it home, and rigged up one of my famous "stick in a vase" arrangements.
We do something similar to this for our "Easter tree" every year, but we embellish it with little hanging bird and egg ornaments and a bit of dried grass or greenery in the base. This picture is a little dark, but you get the idea.
Just find a not-too-fancy glass vase (straight vases with smaller necks work best) and dump in some gravel. Or decorative stones, if you have a bigger budget. I collected all white rocks from our gravel driveway, which worked surprisingly well. Fill the vase about 1/3 full and then push the base of your branch or branches in as far as you can. Keep dumping handfuls of rocks around the "trunk" so it doesn't shift. This is one vase that your cat won't be able to tip over!
