Weighted blankets have long been used therapeutically for people with sensory sensitivity or restless leg syndrome, as well as to increase focus (particularly in classroom settings). Newer studies are finding that these heavy blankets increase serotonin and melatonin levels while also lowering cortisol levels. Your mood improves, and because the weight minimizes movement during sleep, it helps your body stay in a deeper sleep for longer.
I have several family members who struggle with sleep and/or anxiety, so weighted blankets sounded like an amazing solution. I was sold--but yikes! This blanket carries a price tag of nearly $300. I set out to make my own with a budget of $50, using plastic pellets for the weight.
After enjoying my weighted blanket, I can honestly say that all the advertised hype was true. Getting lazy underneath a blanket while reading a book or watching TV is super relaxing, and seems to ease my muscles. I tend to move around a ton while sleeping or sitting, but with the blanket on I can stay in the same position for hours (and I find that I'll spend more time reading without my brain and body getting distracted). The only "problem" is that my children and husband also find the blanket to be deeply comforting; we often argue about who gets to use the blanket while we all relax in the living room together.
I should say that while this is primarily a sewing project and may appear intimidating, I am not a strong sewer. This project is great for anyone with a sewing machine who can sew mostly straight lines.
Tools and Materials
Water-soluble Fabric Pencil
Metal Ruler (optional)
Plastic Pellets - This is where our blanket gets its weight. Follow the general rule of 15lbs for a person weighing 100-150lbs, 20lbs for 150-200, and 25lbs for 200+. Make sure to buy pellets that are washer and dryer-safe. I found the cheapest source to be Etsy, where I bought 20lbs of polymer pellets for around $38. Pellets are also available on amazon and through other craft suppliers.
5 Yards of Fabric - This will make a blanket that is roughly twin bed size. I used a quilting cotton because it was inexpensive and light-weight, plus there are so many fun and crazy prints to choose from. As I anticipated my blanket getting a lot of use from everyone in the family, I opted for a dirt-and-stain-hiding dark print.
Plastic Tubing (optional) - if your fabric of choice is textures or fuzzy, the plastic pellets will have a hard time getting to the bottom of the sewn channels. If you find your pellets getting caught, buy a seven-foot piece of inexpensive plastic tubing from your local brewer's supply store that fits onto the bottom of your funnel.
Thread - You'll need two rolls
Step 1: Sew the Basic Blanket
Cut your fabric in half so that you have two pieces that are 2 and a half yards long. Place the right sides of your fabric together. Pin around both long edges and one short edge, leaving one short end of the blanket (the top edge) open.
After you've sewn a big U, clip your corners to ensure that they are nice and crisp. Turn the blanket inside-out and push the corners out until they are sharp. Iron the sewn edges.
Now, put one corner of the open top edge on the ironing board. Fold the raw edges inside about a quarter-inch. Working from one corner to the other, iron down the edges.
Take the blanket back to the sewing machine and sew a half-inch border around the bottom and sides of the blanket.
Step 2: Sew Vertical Rows
Take your fabric over to the sewing machine. Starting at the bottom of the blanket, sew along your marks from the bottom all the way up to the top. Then keep sewing for what seems like forever until you have sewn inch-wide channels across the entire blanket.
Step 3: Fill and Sew Horizontal Rows
Time to get some weight in this blanket! If you use a smooth fabric like I did, insert the end of your funnel into the first row and slowly pour about 1/8th cup of beads into the funnel. If you used a more textured or fuzzy fabric, slide your piece of plastic tubing down into the first row until you reach the bottom of the blanket, attach the funnel at the top, and pour in the plastic pellets.
Shake the funnel and blanket up and down a bit to shake the pellets down into the channel (don't worry about getting the pellets all the way down to the bottom yet, just get them into their channel and out of the funnel). Move the funnel into the next channel and repeat, over and over, until you've poured pellets into each channel.
Pick up the top corners of the blanket and let the bottom of the blanket hang just above the floor. Shake the blanket up and down until all of the pellets shake into the very bottom of the blanket.
Unless you have flawless sewing skills or are a sewing robot, it is likely that your sewn channels are not all exactly one inch apart the entire way from bottom to top of the blanket (mine certainly weren't). This means that even though you are putting the same measurement of pellets into each row, they will not fill up equally. Lay your bottom row with all the filled-up pockets on a table and evaluate if the pellets fill the row up to your 6" line. If the pellets do not fill up to the line, grab your funnel and add more pellets (you'll have to shake them down again, so make sure to fill these rows before moving onto dealing with over-filled rows). If it goes over the line, use a metal ruler or your fingers/fingernails to push the excess pellets back up towards the top of the blanket a little bit.
Use your fingers or a metal ruler to help clear beads out of the way until you have a half-inch space above your 6" line with no pellets.
Carefully carry your blanket over to the sewing machine. With the row full of pellets on your left and the unfilled blanket rolled up on your right, start sewing across the blanket. Use your 6" mark as a guide to keep your stitch straight. As you go, keep clearing the pellets out of the way of the sewing machine foot.
Once your row is completely sewn across and the pellets are all safely captured in their new homes, repeat the funnel-pellet-shaking-sewing process over and over and over until you are left with just the top 6" of your blanket unfilled.
As you sew the rows, the blanket keeps getting heavier and heavier and more difficult to work with. I found it best to keep the bulk of the blanket on the left side of the sewing machine; the blanket folds neatly along the sewn 6" lines.
Step 4: Close Top Edge and Get Cozy
Starting at one end, carefully fill the pocket with pellets until it is filled to about a half-inch down from the top of the blanket. Take a sewing pin and weave in and out of the fabric in small increments right up against the packed-down pellets to seal them into the pocket. Continue going row by row, pin by pin, to fill the entire row.
Start carefully sewing the row shut, removing pins as you go. The pins should allow you to sew within one-fourth of an inch from the top edge of the blanket.Move along slowly along the top edge.
After the row is complete, sew right along the very tippy-top edge to give it a crisp, neat close.
Congrats! You're finished! Lay down or sit in a chair and get that blanket on top of you. Chill out and enjoy the natural, medicine-free feelings of relaxation.
