Instead of using tape you could also use some shrink wrap as well. I love that stuff!

Bendable PCV pipe I feel so dumb. Been thinking how to reinforce corners because you can also end up tearing the canopy if too much rain puddles up or just tearing the whole thing down. add some zip ties and the the pipe isn't going anywhere, and a couple snips to remove and take down. Thanks.

great job. a simple solution for what can be a big issue, especially for traders that set up for a week or have their marquee as a more semi-permanent set-up in the garden. Well done

May try this. Usually use pool noodles but my 10x20 has no upper rails to roof, more like a circus and tent with 3 spring posts. Thinking about it now, PEX may be what I need, even if it just simply laid across the upper post supports to provide tension where the sag areas are. Can almost make a whole support frame all the way around. May use wood dowels to join since those t fittings are expensive. PEX B 1/2 x 10 is like 4.50, which is what a single fitting cost.
