Oh wow that is cool. Never thought about that. And it does make alot of sense. Thanks for telling me. :) Happy Quilting.

Never heard of it. Thanks so much. I learn something new everyday on this board. And they say you can't teach an old dog new tricks.. They are mistaking!!!

Autistic spectrum children normally cannot stand to be held and are restless. The weight of the blanket makes them feel held/swaddled and secure. Using the blankets at night mostly insures the child will get a good night's rest. Part of their problem is not being able to get a good night's sleep. Without the proper rest, the child cannot pay attention and learn. If the child isn't sleeping/resting, that means the parents/family aren't sleeping/resting either. I have had several parents tell me that once the blanket became a part of the nighttime ritual, everyone was able to sleep.

I've never heard of these before. :)

This is very interesting. Thanks for the info.

we used muslin (pockets) to hold the pellets inside the quilt top

If the blanket/quilt is for a child with autism, etc., check with the child's doctor to find out how heavy the quilt should be. divide that weight by the total number of pockets you will have to determine how much to put in each pocket. This provides the most benefit to the child.
