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!

Step 1: Materials

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

Step 2: Patch the Holes With Duct Tape

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

Step 3: Filling the Socks

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

Step 4: Finishing

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
