How do you make an arm cast out of a sock?

its very simple! all you need is about 11 socks and a saftey pin

step 1: wrap two socks on your wrist

step 2: wrap two socks on your fore arm

step 3: wrap two socks on your elbow

step 4: wrap two socks above your elbow and then clip them all together with a saftey pin

step 5:wrap the remainder of your socks above your other socks :) hope this helped! adiOS amigos!
