Fast, Easy and Cheap Wrist Rest

I have just started a new degree in computers, not a university, but is something. I have to spend hours and hours in front of a screen and I don't have a proper desk to stay confortable with my keyboard. I don't have money, I'm spanish and the crysis is hitting us very hard.

So, I've just build this wrist rest, is cheap about 1€/$ (recycled materials) is easy to do, and you'll finis it in less than 5 minutes. Here we go!

You will need:

A pair of old socks, doesn't mind if they are ripped. Mine are made of wool, extra warm.
Duct tape
Rice
Thread and needle

Title says all flip the socks and path, you don't want all the rice on the floor.

Flip'em again and put some rice. I filled half a sock, and I spent a whole box of rice. I said this project will be cheap, so I stopped pouring there, also I ran out of rice

Seal the "rice sock" with some duct tape and cover it with the "non-rice sock". I used the ripped sock as the "rice sock" because is uglier. I finished without sewing because i don't know how to sew at all, but i recommend to sew the end of the "non-rice sock" after covering the "rice sock" for a better finish.

Will be a great project with a pair of two new socks, instead of some worn out ones. But you know, money is the king...

BTW this is my first real 'ible, all comments are welcome
