Re: Polytunnel puzzle.

Hello Ian,

There are parts you can buy that are used in commercial poly 
greenhouses to hold the plastic to the frame. I believe they are 
metal channels with zig zag springs that secure the plastic into the 
channels. I think they cost less than a dollar per foot.

If you're interested, email me and I'll dig out the particulars.
