Instructions
Gather and Prepare Your Supplies
Pin your fabric, right sides together, along the line you want to backstitch. This keeps the fabric in place and helps ensure a smooth seam. You can remove the pins as you sew.
Cut a length of thread to start. Anything over 24 inches is likely to get tangled and knotted, so stick to shorter lengths.
Thread your needle by moistening one tip of your thread. Insert the moistened end through the eye of the needle and pull to create a 3- to 4-inch tail.
Take the other end and wrap it once around the first knuckle of the middle finger of your non-dominant hand, holding it in place with your thumb. Using your thumb, roll this loop up and off your finger, twisting as you go (you should end up with a loose knot). Tighten the knot by pulling it downward.
Sew the Backstitch
Start at the top of the seam line you want to sew. Insert the threaded needle from the bottom side of the fabric and push it through to the top.
Pull from the top until the knot catches.
Insert your needle about 1/8 inch below the position where the thread came out in the first step.
Grab the needle from underneath (holding both ends of thread at the base of the needle securely) and pull it taut.
Insert the needle 1/8 inch below the last needle hole and pull it through the top, again holding the thread securely at the needle's base.
Insert and push your needle through the fabric at the bottom end of the stitch that is showing on top of the fabric.
Repeat this process until you've reached the end of the area you want to sew together.
Push the needle through to the bottom side of the fabric and run it under the previous stitch.
Pull it taut and cut the thread to leave a 1- to 2-inch tail.
