MYOG: 3mm Plastic Tarps

[Ronald Probst]

For those who, like me, don't make their own gear, this approach is useful to "prototype" manufacturers' shaped tarps. I'm just at the height where reviewers say "taller people may find this setup confining" so I like to "try before I buy". Manufacturer dimensions plus BPL review measurements, and a little geometry, enable a layout on sheet plastic. Straight lines and flat panels are good enough for this "fit check". These have just been backyard try-outs, but enough to eliminate a couple of purchases that I probably wouldn't have been happy with, and find out what works for my height even if it's heavier.

Another thing you can try, is to just have twine where the ridgeline and corners are to get an idea if it's big enough,

easier than doing a plastic sheet

As Jerry suggests, I use very thin sewing thread if I want to know how the dimensions will come out when I start with a new project.

This is a picture of the front-extension I was going to make for my GoLite Lair 1. I hope the thread is visible.

Edit: to have a bit more contrast in picture – as I supposed, the lines where hardly visible (hope it's better now).

[Jerry Adams]

Exactly – I can see the threads – nice picture

I've used 3M packing tape, but prefer Tyvek Tape if available. That stuff is pretty much permanent, just make sure you stick it in the right place the first time, it doesn't like to let go!

This is a very cool article. Nice to know there are other cheap/light freaks out there. I use a piece of plastic (8×12 in the winter) and drape it over a tautline, as shown above, only I leave 3-4 feet on the ground for a ground cover. Big rocks hold the ground cover in place, and the two corners on the other side of the line get tied out with sheet bends- or sometimes just held down with rocks. Under 4 ounces in 3 mil, according to the math above. One of these days I should weigh mine.
Not a perfect cover, but it will get you thru a storm. Yeah, you need to think about where you set up camp, but that's just good sense. Most of the time I would rather look at the stars, anyway, and the plastic is just a ground cover.

That's funny, I figured this subject was so lame nobody would be interested : )

[James Montgomery]

Quite the opposite. Consumerism is lame. Good gear is important, but campcraft rules!
By the way, I've been at this awhile, and a lot of what I read seems written by tenderfeet. Thanx for a competent article.

[Jerry Adams]

The other thing is people's comments – lots of other ideas as good as the article
