My first ever tent making project was the Henry Shires Tarp Tent, and there is a very elaborate and detailed set of plans still available online for it’s construction. I bought a kit years back with all the materials needed, however I am unable to find it online anymore, so perhaps it is no longer being made. The directions are enough to work with though, and you can buy the materials from any outdoor fabric place online, or Amazon.
I made a few alterations to the original design, in hopes to make it a bit more bug resistant. Shires calls for no floor inside the tent, but to place pack items around the perimeter to keep the tent sealed up. I prefer to have a sewn in tub style floor and a completely surprise free tent, so I used a piece of a hardware store tarp. This did add a lot more weight than if I were to have used other fabric, but the extra protection from rocks and the ground I believe to be worth it. In the images I placed the tent on another blue tarp just to keep it clean since I was still working on it. The tent itself has a solid floor made of the same material, so the large blue tarp on the ground in the pictures was only there to keep the actual tent from getting dirty.
In the picture on the left you can see the separate floor that is sewn into the tent, and also how the side screening works. The left side is designed to be lifted during nicer weather to allow air circulation inside the tent. It can also be pitched lower in the case of rain or colder nights. The front beak is not in place to make it easier to see inside the tent, but both the front and rear faces can be completely closed off should a rain storm hit. All in all this is a relatively small shelter, but large enough for one person and their gear to be comfortable. It is very light weight even with the tarp floor in place, and since you can pitch it with a couple sticks that you find on the ground, you really don’t need any tent poles either. This particular tent also rolls down to a very small size, and pretty much disappears inside your backpack. It’s a fun project with an inexpensive price tag.
