If you haven’t tried thrummed knitting before, this is a wonderful technique for creating an extra thick and warm fabric. It’s traditionally been used in hats and mittens.

What’s a thrum?
A thrum is a small piece of unspun roving that is knit into your project. Thrumming makes the insides soft and fuzzy, and incredibly warm.

What kind of wool should I use for thrumming?
To make a thrum you start by pulling of a piece of roving that’s about 3″ long. If your fiber has a staple length that’s much longer or much shorter you might have trouble. Look for a fiber that’s a medium length and soft, after all this will be next to your skin!
