I made this octopus hoodie for a halloween costume a few years ago but I thought it'd be fun to post instructions for it here. You could probably wear it around town as just a regular hoodie too, it's pretty nice and warm.
Here's what you'll need:
A really large hooded pullover sweater
It should be a lot bigger than you normally wear, preferably of just one solid color.
I got mine from the thrift store for pretty cheap.
Some felt, foam, or fleece circle things for suction cups
I used about 40 circles, about an inch and a half in diameter. I was lucky and found this foam mat with big circles in it I just cut out but you could just cut out a bunch of circles from fabric though. Or use real suction cups off a rubber mat, though that's more of a pain to cut out and sew on.
I used scarves and hats but you could also use batting, socks, newspaper, underwear, etc...
I sewed it by hand cause I didn't have a machine so I just had needle & thread, but it would go much faster with a sewing machine. Or if you're really in a pinch, fabric glue.
Step 1: Remove the Front Pocket
I love the little pouch in front of hoodies, but it'll just get in the way here, so let's get rid of it. Cut it out without while making sure your not cutting into the main part of the hoodie underneath it.
