I am a chapter coordinator for Project Linus in my area. We have made over 450 weighted blankets in the last 3 years. We have a pattern that use 2-1yard pieces of fabric. We make tubes and then stuff the tubes with sheets/bath blankets/old towels. I work with occupational therapists in the medical sector as well as the public schools and the recommended weight is 10% of the child's body weight plus 1 pound. The child needs to feel the weight to feel swaddled and secure. If you need any help, please pm me. I have several unfilled blanket shells that are made, just need to be stuffed. All that is required is the postage of $5 for flat rate shipping. Diane
