Wash wool or other fibers for spinning.

Step 5 Storage

I sometimes keep washed fleece in large plastic zipper seal bags while it waits to be spun. This keeps moths out of it and keeps it clean. 

An important trick for long term storage is to put your bags of fiber in a freezer for 72 hours or so, remove them for about the same and then pop em right back in for another 72 hours. This kills any moths or larvae that might have gotten into your precious fleece and wipes out any that may hatch from eggs once they are tricked into thinking winter is over. 

Once you do this, so long as you keep the bag closed, your wool or other fiber should store well indefinitely. Even if I plan on spinning right away I try to keep the fleece in plastic bags to protect it and keep a watchful eye out even after running it through the freezer. I'm probably just paranoid but I hate to lose fleece to bug food.  

Note, you can also do the freezer with finished skeins of yarn if you think moths are attacking it. 

Even with this simple method you can easily stock up a good stash of fiber ready for spinning when the mood hits you.So, Now it's time to learn to card or comb your fleece and get spinning!
