Pluralmolecule over on Instructables has posted a very easy and clever method of spinning yarn out of plastic bags. The supplies are minimal; they include:
- A bunch of plastic bags
- A scissors
- A simple spindle
This how-to does not include an accompanying video, but I found step-by-step videos on joyofhandspinning.com. In them, they are spinning wool, but the technique appears to be the same as in the Instructable post. The website also includes instructions on how to make a drop spindle, which pluralmolecule seems to have used, although, the poster does not refer to it as such.
For more ideas of converting strips of plastic bags into accessories and things, check out this post which includes some great links that provide free patterns.
