I bought a huge wool sweater from the thrift store to make soakers and/or longies and felted it first. I did it twice, thinking it should be reeeally felted. Now it's too small and thick to use!
I've seen a couple people online saying you don't even need to felt the sweater first. You can just cut it and sew and it's fine.
Can anyone here testify they've done that and it works before I go and wreck another sweater?! I'm trying to save money here, and although they're only thrift store ones, the money adds up!
