Plarn! You start with a bag...

... then you fold it up real nice ...

... then you cut it into little strips ...

... twice ...

... then you take two of your little hoops ...

... put them over each other ...

... and pull them through ...

... so that they make a knot, like this.

A really tight knot.

noodle packets can also be plarn.

Here's a bread bag I inadvertently opened up. Did you know they fold lengthways, not sideways?

There's my noodle plarn. Tres boucle.
