I am thinking of making a weighted blanket (they are so expensive to buy) and wondered if anyone else had done this. After watching a few Youtube videos I reckon it looks fairly straightforward, but am a bit unsure about what poly pellets to order. The vids were American, so any suppliers mentioned would not be any good for me, but searching online for UK supplies, the poly pellets I've seen are intended for bean bags so I have no idea if they will be heavy enough, be OK in the washing machine etc. If anyone has any hints or tips I would be very grateful.
