This is a simple Instructable on how to create a wrist-rest that sits in front of your mouse pad. You will need about a quarter of a yard of any type of fabric, some popcorn that is not popped, and basic sewing skills.
I saw that there was another instructable on how to make one of these. But requires more materials, time, and is "for girls " according to my boyfriend. We had the mouse pads with the wrist-rests already on them; but the memory foam wore out really fast and we realized it would be more cost efficient to create our own using a different filler material, and make it last longer.
Step 1: Step 1: Finding the length measurement
Measure your mouse pad to determine how long you need to make the wrist-rest. My mouse pad measured 8 inches across. After you have measured your mouse pad, then fold your material into four layers to make cutting easier. Make sure to add an additional two inches when measuring on the material to allow for the seam when sewing.
I used the four layers for extra protection for losing popcorn kernels, and the added comfort/cushion. You may use more or less layers depending on the type of material you are using. I used a rayon/cotton blend because it stretches easily.
