The blanket stitch is popular for many crafts, not just for edging blankets. It is usually used with heavyweight fabrics like wool, fleece and felt. The blanket stitch creates a row of stitches around the edge of a piece of fabric and a line of thread down the cut edge of the fabric, creating a finished edge.
Blanket Stitch Instructions
Determine the size of stitches you want to make. If you plan to stuff the project you are blanket stitching, you will want to use smaller stitches. The size of stitches refers to both the length of the stitch from the edge of the fabric to the other end of the thread and the distance between stitches.
Start by doubling your thread or floss and making a knot in the end of it. Heavier thread or embroidery floss works best for blanket stitching. You will have a loop of thread with a knot at one end and your needle at the other. Put your needle through from the back to the front of the fabric where you want the bottom of your first stitch to be. Try to hide your knot, which can be between the two pieces of fabric or under a hem.
Moving from left to right (unless you prefer to work from right to left), go 1/4 inch (more or less, depending on your desired stitch size) to the right and up to where you want the non-connected edge of your blanket stitch to be. Run your needle from the front to the back of your fabric. This should mean that your thread is going back through the fabric on the same side it just came from. If you pulled it tight at this point, it would result in a simple, diagonal running stitch. To make this a blanket stitch, instead of pulling the thread tight, move your needle from the back side to the front directly below where you ran your needle from the front to the back, and even with where you started. Put the thread that runs diagonally from the first to the second stitches under your needle. Pull it snug. This should result in a series of stitches that have a line of thread running down one side and gaps between the stitches on the other, resembling even teeth.
Continue stitching until you finish your project. Your stitches should all be the same length and the same distance apart.
