My 2 hats are finished. They are mostly acrylic but 25% wool. Is it necessary or just a good thing to do, to block these hats?

Thanks.

I don't think I'd bother blocking them. I didn't block the hats I recently made with the same blend, and they looked fine. If you wanted to you could throw them in the washer and dryer. It would fluff them up a bit.

Great, Thanks!
