Next to a good traditional picket fence, I love the ornament wire fencing associated with the 1920's. It achieves a beautiful patina over time and offers protection to vegetables while allowing good air flow. This crimped wire fencing also makes the perfect support for trailing sweet peas or clematis, and adds the perfect old fashioned element to a cottage garden.
I kept an eye out at our local salvage stores and even ran ads on Craigslist, but never had any luck finding the vintage fencing (sadly, I'm sure it ends up at a dump when removed from most older homes). I couldn't find any local sellers of the contemporary version, so ended up doing some investigation online. Here are two links from sellers I located. When I ordered mine, it arrived in a big bale, with straps around it!
