I don’t know why I didn’t do this sooner. I have GIANT piles of fleece. You can do this with any material that you want to become yarn. First, figure out which direction of your fleece is the stretchy direction, then fold along the dotted line as shown below.
Second, using a rotary blade (or scissors for a rustic look), cut your material starting from the fold in 1/2 inch ribbons. Stop a 1/2 inch from the edge.
Then, open it us and clip every other edge as in the diagram below.
Next, trim the corners off of each turn like so:
If you have multiple pieces of fleece to join, trim the ends and put a TINY slit in each yarn piece…smaller than shown below.
Next, thread strip 2 through the slit in strip 1 and pull its (2’s) tail through it’s own slit. Check out this post for a good picture of it.
Finally, crochet with it!
