Weighted blankets can help relieve stress, anxiety and insomnia by providing input to the deep pressure touch receptors throughout the body. This "deep pressure touch" helps the body relax. Like a firm hug, weighted blankets can help someone feel secure, grounded and safe. Making your own weighted blanket isn't difficult and can save you money, but does take some time and sewing skills.
Use a medium weight fabric like flannel for this project. You will need at least 2.5 yards for the top and 2.5 yards for the bottom of the blanket. This will give you a blanket about the size of a twin size blanket (if using 44-45 inch wide fabric). Make sure you get the same plastic pellets used to add weight to dolls.
Always pre-wash and dry fabric before you begin.
This blanket is customizable. After you determine the size, measure and cut two pieces of fabric for the top and bottom. Place the fabric pieces together, right sides in. Measure two inches in on both long sides and one of the short sides, leaving one side open for adding your pellets. Use tailor's chalk and pins to mark for sewing.
Before you fill the bottom row "pockets" you will need to figure out the portion of pellets to put in each pocket. To do so, use this formula: total desired blanket weight in ounces divided by number of squares equals number of ounces per square. Place a cup or bowl on a scale and zero it out before you add the pellets.
Remember that 16 US oz. = 1 lb
Keep adding pellets and polyfill, row after row until you have finished the last row of squares at the top. Then, fold in the two inches of fabric that are left over (or however much you have left) and sew it shut. This will seal up the top row of weighted squares.
