A no-sew tie blanket uses knots instead of stitches to hold two layers of fabric together

A no-sew tie blanket is two pieces of fabric—usually fleece or flannel—with the edges cut into strips and tied together in a grid pattern. The knots hold the layers in place and create a textured, finished look. You do not need a sewing machine, thread, or any sewing skill. The whole project takes two to four hours depending on the blanket size.

The reason this method works is that fleece and flannel do not fray when cut, so the raw edges stay neat without hemming. The tied knots are strong enough to hold the layers through washing and years of use. This makes it one of the fastest ways to turn fabric into a finished blanket.

Key Takeaways

  • You need two pieces of fleece or flannel the same size, scissors, and a ruler or measuring tape—no sewing machine required.
  • Cut 4-inch strips around all four edges of the fabric, then cut 4-inch squares into the interior in a grid pattern about 6 inches apart.
  • Tie the matching strips from the top and bottom layers together using a square knot, working from one corner across the entire blanket.
  • A standard throw blanket uses two 60-by-50-inch pieces of fabric and takes about 100 knots to complete.

What you need to gather before starting

Buy two pieces of fleece or flannel fabric cut to the same size. A standard throw blanket is 60 inches by 50 inches; a larger bed blanket is 90 by 90 inches. Most fabric stores will cut fabric to size for free if you ask at the counter. Fleece is cheaper and warmer; flannel is softer and more breathable. Either works equally well for a no-sew blanket.

You also need sharp fabric scissors (regular scissors work but dull faster), a ruler or measuring tape, and a pen or fabric marker. Some people use a rotary cutter and cutting mat to speed up the process, but scissors are fine. Lay out a large, clean floor or table—you need room to spread the fabric flat.

How to cut the edges and interior grid

Stack the two pieces of fabric on top of each other with the edges aligned. Using your ruler and pen, mark a line 4 inches in from each edge all the way around the blanket. This marks where your edge strips will be. Cut straight lines from the outer edge toward the marked line, stopping at the line. Space these cuts 4 inches apart. You will end up with 4-inch-wide strips hanging off all four sides.

Next, mark a grid on the interior of the blanket. Start 6 inches in from one corner and mark points 6 inches apart in both directions across the entire blanket. At each marked point, cut a 4-inch square through both layers. Cut straight down and across to make a small square hole, not a circle. These squares are where you will tie the knots. The grid does not have to be perfect—the blanket will look fine with slight spacing variations.

Tying the knots along the edges

Start at one corner. Take the two strips hanging off the top layer and the two strips hanging off the bottom layer at that corner. You will have four strips total. Tie the top-layer strips together with the bottom-layer strips using a square knot: pull the top-right strip and bottom-right strip together, cross them over the top-left and bottom-left strips, pull tight, then cross them back and pull tight again. This creates a knot that will not come undone.

Work your way along one edge, tying each pair of strips to the pair directly below it. When you reach the end of that edge, move to the next edge and repeat. Tie all the edge strips before moving to the interior. This keeps the two layers aligned while you work on the grid.

Tying the interior grid knots

Once the edges are tied, move to the interior squares. At each 4-inch square you cut, you will have four flaps of fabric—two from the top layer and two from the bottom layer. Tie the top-layer flaps to the bottom-layer flaps using the same square knot. Pull the knot snug but not so tight that you distort the fabric.

Work systematically across the blanket row by row so you do not miss any squares. If you have a large blanket, you may want to tie every other row first, then go back and fill in the gaps. This prevents the fabric from shifting as you work. Each knot should be visible and roughly the same size.

Finishing and washing your blanket

Once all knots are tied, trim any uneven strips with scissors so they are all roughly the same length—about 1 inch is standard. Shake out the blanket and lay it flat to check that all knots are find and the blanket lies flat. If any knot feels loose, retie it.

Wash the blanket in cold water on a gentle cycle before using it. The first wash may shed some loose fibers, which is normal. Dry on low heat or lay flat to dry. The blanket will soften with each wash. Retie any knots that come loose after washing, though this is rare if you tied them tightly the first time.

Common mistakes and how to avoid them

The most common mistake is cutting the interior squares too small or too large. Four inches is the sweet spot—large enough to tie comfortably but small enough that the blanket stays together. If your squares are 2 inches, the knots will be fiddly. If they are 6 inches, the blanket will have gaps.

Another mistake is spacing the grid too far apart. Six inches between knots is standard for a throw blanket; if you space them 12 inches apart, the blanket will bunch and shift in the wash. For a bed blanket, you may want knots every 4 inches instead to keep the weight distributed evenly.

Do not use cotton fabric for a no-sew blanket. Cotton frays when cut, so the edges will look messy and the blanket will shed threads. Fleece and flannel are the only fabrics that work well for this method.

Frequently Asked Questions

Can I use regular cotton fabric instead of fleece?

No. Cotton frays when cut, so the edges will look unfinished and shed threads. Fleece and flannel do not fray, which is why they work for no-sew blankets. If you want a cotton blanket, you will need to sew the edges or use a different binding method.

How long does a no-sew tie blanket last?

A well-tied blanket lasts for years with normal use and washing. The knots are as strong as seams if tied tightly. Occasionally a knot may loosen after many washes, but you can retie it in seconds. Most people find their blankets outlast their interest in using them.

What size fabric should I buy for a baby blanket?

A small baby blanket is typically 36 by 36 inches, which uses two 36-by-36-inch pieces of fabric. This takes about 25 to 30 knots and takes 30 to 45 minutes to complete. Make sure all knots are very tight so they cannot come loose if the baby pulls on them.

Can I tie the blanket with embroidery floss or yarn instead of fabric strips?

You can, but it is not necessary and takes longer. The fabric strips are already there when you cut the grid, so you just tie them. Using separate yarn means threading and tying each knot individually. Stick with the fabric strips for speed.

Do I need to hem the edge strips after tying?

No. Fleece and flannel do not fray, so the raw edges stay neat. The tied knots hold everything in place. You can trim the strips to an even length for a cleaner look, but hemming is not necessary.
