Tailor-made Heating Pad Cover

I like using hot-cold packs to keep my knees warm in winter when I'm watching television.
However, because I find it annoying that I have to keep still/lie still to avoid the hot-cold pack from slipping off, I decided to make a "tailor-made" cover for my knees.

This instructable shows a step by step to make one for yourself, or as a gift for someone.

To make a "tailor-made" hot-cold pack cover, you need:
- A tape measurer;
- Needle, thread (and a sewing machine if you have one);
- Scissors;
- Velcro;
- A hot-cold pack (or heating pad);
- Towel and fleece fabric.

This is actually a great project if you have an old towel you want to "recycle".
