What kind of PVC piping did you use to form the arch?  When I went to the hardware store, they told me that PVC piping does not bend.

Thank you.

we used schedule 40 1/2 inch pvc, 10 ft lengths bent just fine.

This was perfect—thanks.

Also: we love the bobbing toucan—where to find?

The video actually said use 1/2” rebar and 3/4” pvc. The 10’ length is also important to know for the optimum arch height, for the 4’ raised bed.

Note 1/2” pvc can not handle as much snow load. Plus finding smaller rebar than 1/2”  may be difficult.
