It's not that hard to fix them yourself. Just strip it down to the frame, redo the rubber if needed and sit down to watch TV with a trap in front of you. A link to instructions is
HERE. Practice making the netting in a straight row first. I used a Formica sample from the store as a gauge stick. The first one will be a bit challenging as you learn to fit the netting on as you weave. If you know somebody that knits or does macramé they could help you learn. After the first one you'll be an expert! And I live in the Portland area so the knowledge knows no bounds.
