#tents

Trunks, cases and a couple of tents. Clichés & gravures v.1. Cuts & engravings. 1912. Specimen book.

Like it's more convenient to buy one already made, but if you've got a cool shape in mind you can order canvas or ripstop nylon and poles and just sew the dang thing yourself.

Classic designs are really simple (a wedge tent is pretty much just one folded piece of fabric with a front and a back sewn on, with the front slitted to make a door).

There's a little more engineering involved depending on your goals but it's all stuff you can figure out pretty easily, and if you need something up you can likely reuse the pieces as part of a later design.

The standard canvas to use is called "cotton duck", and if you pay a bit extra you can even get it pre-treated with waterproofing. But if you don't, you can also waterproof it yourself.
