So here's there the front part of the rainbow sock with toes ( I personally like the toes part! )
& here's the back part where the heel is .
First , you have to cut off the toes part .
Just the tips though , you want your fingers to be able to have seperate
& so this is what it'll look like :D
Now flip it over to the back so you can work on the heel bit .
Lay it flat , the heel part will tend to stick out .
Just fold it in .
Once you've fold it in & are happy with how it looks , it'll look something like this .
Then sew the gap shut however you like .
Ok , so I'm not good at sewing , but heck it was an attempt :p
Just as long as it's sewn shut & doesn't stick out , it's all good (:
After sewing ;
It'll look like this .
It's not perfect but it works .
& there you go :D
