I moved into a new house about 6 months ago and my Aunt gave us a few extra packages of window sheers she had in case we needed them. We didn't and they have been kicking around all that time. I finally decided to open one up and take a look at them to see if they were thick enough to use for rags. Turns out they are WAY to thin for rags but they had loops sewn into the tops and bottoms and each edge is nicely hemmed. They are very similar to some DIY hammocks that I've seen online.

Step 1: Material
Window Sheers, mine were 60" x 84" and came 2 per package
Thin rope "i had some paracord so that's what I used"
2 disposable rubber gloves - may not be required for your setup.
