I made a weighted blanket for my grandson who is autistic. I cut 2 pieces of flannel the size I wanted the quilt (40 x 40). one for the front and one for back. sew the three sides leaving the top of the quilt open. now run seams down the blanket to make about 6 channels (vertical seams). Then I put plastic pellets into the vertical channels. I filled the channels about 6 inches deep, then I sewed a horizontal seam across the width of the blanket ( this sealed the plastic pellets in the 6 inch high channel) Then I filled another 6 inches of channels and then sewed another horizontal seam across blanet, continued till blanket was filled to top then added binding all around edges. The pellets I got from Joann's with 40% coupons, they wash and dry nice. good luck if you need help pm me
