While you can buy a cheap tarp for around $13 (and that's at the pricey end), they're waterproof, protect you from the sun, can do a number of other things, and if you get an 8' x 10' they weight about 1.3lbs.
While that may seem light, there are those who want it to be even lighter. And so, there is a DIY method you can use to do that! Using a bed sheet and silicon it's possible.
You'll need to pick up:
- a bed sheet!
- 30 oz mineral spirits
- 10 oz silicon sealant (usually used with a caulk gun)
1. Mix the mineral spirits and silicon sealant together in a 5oz bucket.
2. Stick the bedsheet in and swirl it around!
3. Once covered, hang the sheet on a clothesline to dry.
