Thanks! I will research more as I would like something that can be easily washed as she likes to be covered while she eats sometimes. I will ask the therapist Monday when we go back what she recommends.
The pattern I found was the one with the columns then you sew as you fill to make squares through out the blanket. And I did read where it should be 10% of the body weight plus a pound.
Thanks again for all the info.
