You could also make him one for his neck that hangs down a bit .Those come in handy for T.V watching . My nephew is Autistic & I have made him both , they really do seem to help. I also made him a vest but instead of plastic pellets I used BB shot for it,The blankets & neck ones are easy . I cut a top & a bottom size I want the blanket or scarf to be.Sew around all 3 sides with right sides facing each other . I turn right side out & sew a seam from top to bottom down the middle .Then I measure fabric & sew seams 4-5" apart all the way across , then I add 2-3 Tablesoons of the pellets in each row Then I take a golf size or a little larger of batting & put 1 in each row on top of the pellets & sew from on side to the other the same distance that I the up down rows.Continue until at the top & sew 4th side together . Make SURE there is NO WAY YOUR PELLETS CAN ESCAPE. These make the kids feel hugged & secure .( Adults too .
