Re: Building a large spire out of blocks of eggcrate, what to do about the sides?
Thank you for your input. I've been considering the ups and downs of what you suggested for the last hour or so.
First, I don't think it's too late for me to back out of using eggcrate, aside from that I don't know what I'd do with the eggcrate spire I've already made. It only took 3-4 hours, so it's far from the most time-costly part of this project even at this point.
There are two reasons I didn't use styrofoam / EPS foam in the first place:
1) I'm likely to have "gullies" or depressions of some form for terrestrial plants that collect water in the substrate and don't drain through styrofoam, and I don't want to redesign the spire to have no places in which water doesn't drain. Eggcrate + Mosquito netting doesn't have that problem (unless I'm careless with whatever I put over it).
2) More importantly, there are a lot of things about paint / epoxy / mortar / cement that I don't understand in relation to styrofoam. I have a lot of experience with spray foam, silicone, coco/peat backgrounds, eggcrate, and netting, but I really haven't been able to find out how to use other substances well. (I did read your link, but I had trouble understanding some of the concepts. I don't quite understand, for instance, how epoxy and styrofoam pearls could ever be combined into something craftable.)
If I could address those issues somehow, I'd be more than willing to switch to styrofoam; I even have a supply of it in reserve right now. But there are many things that I can't really visualize adequately. Can I just use superglue to attach layers before I carve them? Can I carve them with just a sharp pocketknife, or is there some method even better? How do I texture trees / roots / rocks / an islandscape like this? What kind of paint is realistic-looking?
Again, thank you for that information. I'm certainly willing, if not yet able. I'll re-read your link and see what I missed.

Reason: Clarification about "gullies" / depressions.
