Re-using yarn

[mojo11]

It's usually called 'yarn barf'.

Not exactly the term I was thinking of, but it works.

That's the politer term...

The method I always use with great success is to bend my arm at my elbow and wrap the yarn around my palm and under my elbow, forming a really long loop. I drape it over the hook of a coat hanger, hang it from the shower curtain rod, and then steam it carefully with an iron. You could also skein it and give it a quick soak in some warm water, roll it in a tower to squeeze the excess out, and then hang it to dry, but it takes longer that way.
