In medicine, a surgeon's knot is used to secure suture threads during surgical procedures. However, surgeon's knots are also one of several types useful for making jewelry and working with beads. It's similar to a square knot, but it has an extra pass-through on the first half of the knot. This makes the cords less likely to slip, both while you are tying the knot and once the knot is complete. For a little extra security when you're done with the knot, apply a bit of GS-Hypo Cement or clear nail polish to the top.
Surgeon's knots are a good knot to use with elastic cord. The extra pass-through at the base will help to keep the knot in place while you are tying the second half of the knot. It also makes the knot less likely to untie.
Surgeon's knots work well with beading thread such as Nymo or FireLine. They can be used to add a thread to a component, as in brick-stitched bead-wheel earrings. A surgeon's knot can also be used on the thread end to make a bulkier knot that resists slipping through the beading foundation when doing bead embroidery.Continue to 2 of 4 below.

Starting the Surgeon's Knot
Cross the cord on the left over the cord on the right. Then wrap the cord on the right side over the cord in your left hand and bring it back up through the middle.Continue to 3 of 4 below.

Make the Second Loop for the Surgeon's Knot
The surgeon's knot has one additional pass-through on the first half of the knot. While still holding the cord from the last step, pass it over and around the other cord one more time. With this, you have made a total of two wraps around the cord.Continue to 4 of 4 below.

Finish the Surgeon's Knot
Depending on the beadwork stitch being used, a surgeon's knot may be used to join two ends of beading thread together, such as when tying off the threads or adding a new thread. Using it in this way would depend on having enough room between the beads to add the knot.
Surgeon's knots are not decorative. It is best to use them when you can hide the knot inside of the beadwork or inside of a bead. The surgeon's knot is slightly larger than other knots used in beadwork, so be sure you can pull it inside the hole of the beads you are working with.
Finish the surgeon's knot by bringing the right side of the cord over the top of the left and then wrapping it around and through the middle of the knot. Pull on each side of the cord to secure the base of the knot.
