I use a weighted blanket and vest all the time, it is life changing personally. I recommend sensory goods. They are the most cost effective I've found. Also I bought a sewing machine, and am making them out of rice, I want to give them away, and see if other people want to make them too. They aren't just helpful for autism either, people with PTSD, general anxiety, and many others have said it has helped them. I am trying to find the most cost effective way to make them. Because even the cheaper places for an adult blanket charge close to 200 $. And I think something as helpful as this should be available for anyone who needs it. Anyone have any suggestions on fabric, or any ideas? Or want one, it will be a bit before I get it down, but I will mail it to people for free when I get the material. I know poly pellets are machine washable but duvets or pockets to remove the weighted portion allow you to use rice, which is way cheaper. The laundering is the main concern I have found, I am not dead set on rice, but poly pellets are expensive which is why I think these places charge so much.
