I love it! I ordered the 20 pound adult sized for a twin bed. This was the heaviest weight available. I bought it from SensaCalm online. I've used it to rest under during the day when I'm tired and stressed, and it is wonderful.

I feel I probably have always had ADHD. I also tend to obsess about things. The blanket is very comforting.

There are many instructions for making your own weighted blankets online.
I already have some of the poly beads, which I had ordered for making bean bags. These poly beads are not very expensive, so if you have a sewing machine and some fabric, making one would not be too hard. The poly beads would be the best choice, but I saw instructions for using everything from peas to modeling clay in plastic zipper bags!
