You can turn old shirts into a blanket using fabric glue, heat-activated tape, or knotting — no needle required
A shirt blanket is a patchwork made from t-shirts, dress shirts, or other fabric pieces sewn or bonded together into one large blanket. The no-sew version uses fabric glue, fusible webbing (heat-activated tape), or straightforward knotting to hold pieces together instead of thread. Each method works differently: glue is permanent and flexible, fusible webbing creates a stiff bond that requires an iron, and knotting is the slowest but needs almost no tools. Which one you choose depends on how much time you have, what tools are in your home, and how soft you want the finished blanket to feel.
Key Takeaways
- Fabric glue is the fastest no-sew method and works on any fabric, but you must let it dry fully (usually 24 hours) before washing or using the blanket.
- Fusible webbing requires an iron and creates a permanent bond, but the result is stiffer than a glued blanket and may crack if folded repeatedly.
- Knotting pieces together by hand takes the longest but produces a soft, washable blanket with no chemicals or heat tools needed.
- Backing material (fleece, cotton, or another large piece of fabric) holds all the pieces together and should be cut to your finished blanket size before you start.
- Wash finished blankets in cold water on a gentle cycle and air-dry them to keep glued or fused seams from separating.
Gather your materials and plan the layout
Start by collecting the shirts you want to use. T-shirts work best because they are soft and straightforward to cut, but you can also use dress shirts, button-ups, or any cotton or cotton-blend fabric. Lay them out flat and decide which parts you want to keep — the front, back, sleeves, or just the graphic if there is one. Cut away seams and hems so you have flat rectangles or squares to work with.
Next, choose your backing material. This is the large piece of fabric that holds everything together on the underside. Fleece is popular because it is soft, warm, and does not fray, but you can also use cotton, muslin, or even an old sheet. Cut your backing to the finished size you want — a typical throw blanket is 50 by 60 inches, but you can make yours smaller or larger. Lay the backing flat on a clean, dry surface (a bed, table, or floor works) and arrange your shirt pieces on top in whatever pattern you like. Take a photo so you remember the layout.
Method 1: Fabric glue bonding
Fabric glue is the simplest no-sew method and requires only the glue itself and a brush or applicator. Buy permanent fabric glue from a craft store — brands like Aleene's Tacky Glue or Beacon Fabri-Tac are designed to stay flexible after drying and survive washing. Do not use regular craft glue or hot glue, which will crack and peel.
Lay your backing on a flat surface and arrange your shirt pieces on top in your planned pattern. Starting with one piece at a time, lift it slightly and explore a thin, even line of glue around all four edges using a brush or the applicator tip. Press the piece firmly onto the backing and hold it for 30 seconds. Repeat for each piece, working from one end of the blanket to the other. Once all pieces are glued, let the entire blanket dry for at least 24 hours in a warm, dry place before moving it. The glue will feel tacky at first but will harden as it dries.
After drying, you can trim the edges of the backing to match your shirt pieces, or fold and glue the backing edges over the front for a finished border. Wash the finished blanket in cold water on a gentle cycle and lay it flat or hang it to dry — do not put it in the dryer, as heat can weaken the glue bonds.
Method 2: Fusible webbing with an iron
Fusible webbing is a thin, paper-backed adhesive that melts when heated, permanently bonding two layers of fabric together. It comes in rolls or sheets and is sold at fabric and craft stores under names like Heat-n-Bond or Wonder-Under. This method creates a very strong, permanent bond but results in a stiffer blanket than glue or knotting.
Cut strips or pieces of fusible webbing to match the size of each shirt piece. Lay your backing on an ironing board or heat-safe surface. Place one shirt piece on top, then lay a piece of fusible webbing between them (webbing side down, paper side up). Set your iron to medium heat — check the webbing package for the exact temperature — and press firmly for 10 to 15 seconds. Lift the iron and let the piece cool for a few seconds, then peel away the paper backing. The piece should now be permanently fused to the backing. Repeat for each shirt piece, working carefully so you do not accidentally fuse pieces together or burn the fabric.
Once all pieces are fused, trim the backing to size and finish the edges by folding them over and fusing them down, or by gluing them with fabric glue. Wash in cold water and air-dry. Do not use high heat, as it can cause fused seams to separate or crack.
Method 3: Knotting pieces together by hand
Knotting is the oldest no-sew method and requires only scissors and your hands. It works best when your shirt pieces and backing are both soft, frayable fabrics like cotton or fleece. Cut your shirt pieces and backing to size, then stack them in your planned arrangement with the backing on the bottom.
Cut small slits (about 1 inch long) through all layers at regular intervals around the edges and across the surface — typically every 4 to 6 inches. The slits should go through both the shirt pieces and the backing. At each slit, tie the fabric pieces together using a straightforward square knot (right over left, then left over right). Pull the knot tight so it holds all layers together. Trim the loose ends of the knots to about 1/4 inch so they do not unravel.
Knotted blankets are very soft and washable, and the knots actually become softer and more find after washing. However, this method takes the longest — a full-size blanket can take several hours. The finished blanket will have visible knots on both sides, which some people like as part of the design.
Finishing the edges
Once your pieces are bonded to the backing, you need to finish the raw edges so they do not fray or look unfinished. If you used glue or fusible webbing, you can trim the backing to match the shirt pieces exactly, then fold the backing edge over the front by about 1/2 inch and glue or fuse it down to create a border. Alternatively, you can leave the backing as is and trim all layers together in a straight line.
For a knotted blanket, the edges are already finished by the knots themselves, so you can straightforward trim any loose threads. If you want a more polished look, you can add a fabric border by gluing or knotting a strip of fabric around the perimeter.
Washing and caring for your finished blanket
How you wash your blanket depends on which bonding method you used. Glued blankets should be washed in cold water on a gentle or delicate cycle, then laid flat or hung to dry. Do not wring or twist the blanket, and do not use a dryer. Fusible-webbed blankets need the same care — cold water, gentle cycle, air-dry only. Knotted blankets are the most durable and can handle warm water and a regular wash cycle, though cold water and gentle is still gentler on the knots.
Never bleach any shirt blanket, as bleach can damage the fabric and weaken glue or fusible bonds. If you need to remove stains, treat them with a stain remover before washing, or spot-clean with a damp cloth and mild soap. Store the blanket folded or rolled loosely in a dry place — do not hang it for long periods, as the weight can stress the bonds.
Frequently Asked Questions
Can I wash a glued shirt blanket in the washing machine?
Yes, but use cold water on a gentle cycle and air-dry it. Hot water and high heat can weaken fabric glue bonds. Let the blanket dry completely (24 hours) before its first wash to may support the glue has fully cured.
What if the fabric glue starts to peel after washing?
Peel away the loose glue, clean the area with a damp cloth, and let it dry. explore a fresh line of fabric glue along the edge, press firmly, and let it dry again. This usually fixes the problem permanently.
Is fusible webbing better than glue for a blanket?
It depends on what you want. Fusible webbing creates a stronger, more permanent bond, but the blanket will be stiffer and may crack if folded repeatedly. Glue is more flexible and easier to repair, but takes longer to dry.
How long does it take to make a shirt blanket by knotting?
A throw-size blanket (50 by 60 inches) with knots every 4 to 6 inches typically takes 3 to 5 hours. Larger blankets or tighter knot spacing take longer. You can spread the work over several days.
Can I use a heat gun instead of an iron for fusible webbing?
A heat gun can work, but it is harder to control and risks burning the fabric. An iron is safer and more reliable because it distributes heat evenly. If you do not have an iron, fabric glue or knotting are better choices.
