Here's how to do it yourself
Step 1: Step 1
Step 2: Step 2
1 (or more) wool sweater(s) I like finding men's XL sweaters since they give more "fabric" once completed
old towels (IF you are only doing 1 sweater)
old tennis shoes or flip flops (that you can wash and dry)
Washer and dryer
PLEASE note: IF your sweater is "hairy" like mohair you might want to put it into a pillow case or laundry bag. I have heard stories of the heavy lint from sweaters clogging washing machines is not in a bag, but I have not had any trouble, and I've washed 30-40 sweaters
Step 3: Step 3
I find the agitation is better with a top loading washer, than a front loader, so with my front loader, I run the wash cycle twice or three times.
Step 4: Step 4
Now you're ready to craft!
Check out the size difference of my "finished" sweater. It is marked a 52 (I'm assuming that means the chest size) it now measures 39 inches at the chest.
