Satin binding finishes a blanket edge with a smooth, polished look and protects the fabric from fraying

Satin binding is a strip of satin fabric folded and sewn along the edge of a blanket to create a neat, durable finish. Unlike other binding methods, satin binding lies flat against the blanket and gives a professional appearance because the fabric has natural sheen. You can sew it by hand or machine, and the method you choose depends on how much time you have and how much control you want over the stitching.

The binding itself is usually 2 to 2.5 inches wide before folding, and you fold it in half lengthwise so the finished width is about 0.5 to 0.75 inches. You attach it to the front of the blanket first, then fold it to the back and stitch it down by hand or machine. The whole process takes a few hours for a standard blanket, depending on the perimeter and your sewing speed.

Key Takeaways

  • Satin binding is folded in half lengthwise before you sew it, so a 2-inch-wide strip becomes a 1-inch-wide finished binding.
  • You attach binding to the front of the blanket with a 0.25-inch seam allowance, then fold it to the back and stitch it down to complete the edge.
  • Machine sewing the binding is faster but requires careful alignment; hand sewing takes longer but gives you more control and a softer finish.
  • Mitering the corners (folding the binding at a 45-degree angle) prevents bulk and keeps the corners sharp and professional-looking.
  • Pre-pressing the binding fold and using a walking foot on your machine prevents puckering and keeps the satin from slipping.

Measure and cut your satin binding strips

Measure the perimeter of your blanket by adding all four sides. A standard crib blanket is roughly 36 by 48 inches, so the perimeter is about 168 inches. Add 12 inches for overlap and seaming the binding ends together. Cut your satin into strips that are 2 to 2.5 inches wide and run the length of the blanket edge, or cut shorter strips and join them end-to-end with diagonal seams.

If you are joining strips, lay two strips right sides together at a 90-degree angle, draw a diagonal line from corner to corner, and sew along that line. Trim the excess fabric 0.25 inches from the seam and press the seam open. This creates a smooth join that will not show when the binding is folded.

Once your binding strip is the full length you need, press it in half lengthwise with the wrong sides together. This creates a crease down the middle and makes it much easier to fold and attach evenly. Use a medium heat setting on your iron to avoid damaging the satin sheen.

Attach binding to the front of the blanket by machine

Lay your blanket flat with the right side facing up. Open the folded binding strip so it is flat again, and line up one long edge with the edge of the blanket. Pin the binding to the blanket front, starting at the middle of one side (not at a corner). Sew along the crease you pressed into the binding, using a 0.25-inch seam allowance. This seam will be hidden when you fold the binding to the back.

Use a walking foot on your machine if you have one—it feeds both the blanket and the satin evenly and prevents the satin from slipping or puckering. Sew slowly and stop every few inches to smooth out any wrinkles. When you reach a corner, stop 0.25 inches before the corner point, backstitch, and remove the blanket from the machine.

Fold the binding up at a 45-degree angle to create a diagonal fold at the corner, then fold it back down so it lines up with the next edge of the blanket. This is called mitering and prevents the binding from bunching at the corners. Pin the mitered corner and continue sewing down the next side. Repeat this at all four corners.

Fold the binding to the back and stitch it down

Once the binding is sewn to the front of the blanket all the way around, trim any excess thread and press the seam flat with your iron. Fold the binding to the back of the blanket so the folded edge of the binding covers the seam line you just stitched. The binding should wrap around the edge and lie flat on the back without any gaps or overlaps.

Pin the binding in place on the back, working around the entire blanket. At the corners, the mitered fold you created on the front will naturally fold into a neat triangle on the back—pin it so it stays in place. Once everything is pinned, you can stitch it down by machine or by hand.

To stitch by machine, use a straight stitch very close to the inner folded edge of the binding. A topstitch needle (size 90/14) and matching thread make the stitching less visible. Sew slowly and use the walking foot again to keep the layers from shifting. To stitch by hand, use a ladder stitch (also called an invisible stitch) with thread that matches the satin. This stitch runs inside the fold of the binding and is nearly invisible from the front.

Hand-sew the binding for a softer, more flexible finish

If you prefer to hand-sew the entire binding, the process is slower but gives you more control and a softer edge that moves with the blanket. Attach the binding to the front by hand using a running stitch along the crease you pressed into the binding. Use a needle that glides through satin easily—a size 7 or 8 between needle works well—and thread that matches the satin.

Make small, even stitches about 0.125 inches apart. Sew slowly and keep tension even so the stitches do not pucker the fabric. When you reach a corner, fold the binding at a 45-degree angle as you did for machine sewing, and continue stitching down the next side.

Once the front is complete, fold the binding to the back and pin it in place. Use a ladder stitch to close the binding on the back. Bring your needle up through the fold of the binding, then insert it directly across into the blanket fabric and run it inside the blanket for about 0.25 inches. Bring the needle back out and insert it back into the fold of the binding. This stitch is nearly invisible because the thread runs inside the fold and inside the blanket layers.

Miter corners to keep them sharp and prevent bulk

Mitering is the technique that makes binding corners look professional. When you reach a corner while sewing the binding to the front, stop your stitching 0.25 inches before the corner point. Backstitch to find the thread, then remove the blanket from the machine.

Fold the binding strip up at a 45-degree angle away from the blanket, creating a diagonal fold. Then fold the binding back down so it lines up with the next edge of the blanket. The fold you just created sits at the corner and forms a neat diagonal line. Pin this fold in place and resume sewing from the corner point down the next side.

When you fold the binding to the back, the mitered corner on the front naturally creates a mitered corner on the back as well. The two folded edges meet at a 45-degree angle and create a flat, square corner with no bulk. This is why mitering is worth the extra few seconds at each corner—it keeps the binding from bunching and makes the blanket lie flat.

Press and finish the blanket

Once all the binding is stitched down on the back, press the entire blanket with a medium heat iron to set the stitches and smooth out any wrinkles. Press from the back first, then flip it over and press the front. Pay special attention to the corners and the seams where the binding meets the blanket.

If you used a machine stitch on the back, you can topstitch the front edge of the binding as well for a more finished look. This stitch runs along the outer edge of the binding on the front and frames the blanket. Use matching thread and a straight stitch, and sew slowly to keep the line even.

Trim any loose threads and give the blanket a final press. The binding should lie flat all the way around, with no puckering, gaps, or wrinkles. If you see any loose spots, you can hand-stitch them down with a ladder stitch and matching thread.

Frequently Asked Questions

Can I use a different fabric instead of satin for binding?

Yes. Cotton binding is more durable and easier to sew, though it does not have the sheen of satin. Silk binding looks similar to satin but is more delicate. Bias tape (pre-made binding) saves time but is usually narrower and less flexible than satin strips you cut and fold yourself.

What do I do if the satin binding puckers while I sew?

Puckering usually happens when the satin slips under the presser foot or when you sew too fast. Use a walking foot, sew at a slower speed, and press the binding flat before you sew. If puckering happens, you can remove the stitches, press the binding again, and re-sew. Satin is forgiving and does not show needle holes after pressing.

How do I join the two ends of the binding strip together?

Overlap the two ends by about 1 inch on the back of the blanket where the seam will be hidden. Fold both ends under 0.5 inches and pin them so they meet end-to-end. Stitch across the overlap by hand or machine, then fold the binding to the back and stitch it down as usual. The seam will be hidden inside the fold.

Do I need to pre-wash the satin before I sew?

Pre-wash satin in cool water if the blanket itself will be washed. Satin can shrink slightly, and washing the binding before you sew prevents it from shrinking after the blanket is finished. Lay it flat to dry or hang it to avoid wrinkles.

What stitch length should I use on my machine?

Use a stitch length of 2.5 to 3 mm for satin binding. This is slightly longer than a standard stitch and prevents the needle from creating too many holes in the delicate fabric. Test on a scrap of satin and blanket fabric first to make sure the stitch looks even and does not pucker.
