Here's another one from SewforEasy. She couches a muslin pellet-filled duvet type of insert into the two fabric layers which might be another consideration, particularly when it's time to wash the quilt. Also on YouTube:

A bit of effort, but I understand the quilts are greatly effective for the stressed, emotionally challenged, etc. of all ages (say 3 years on up), She also gives a guideline that the added weight should equal about 10% of the person's body weight.
You go, Girl!
This has sparked my imagination and I might see what the need is in our community.
