I used 550 paracord bought at Barre ArmyNavy to make this. The beads for the eyes as well as the metal barrette came from Walmart in the craft section.
Length of cord needed is determined by how long you want the dragonfly to be. The formula for cord needed is (length of dragonfly body) x (10). For example, if you wanted the dragonfly to be 4 inches, then the total length of cord to cut off would be 40 inches of cord. For a 3-inch, total length would be 30 inches and so on.
This can also be made without the barrette and makes a nice little key chain fob. I included this pic below. Also, it can be made with multiple colors. You just have to fuse the colors together at some point.
This is a series of loose and tight cobra knots. I did not include the tutorial for the cobra. You can either look that up or try and figure it out from the pics here.
Step 1. Find the length of the dragonfly (your preference) and then multiply that length by 10. Cut that much cord off. Slide the beads down to form this shape. The beads should be set at the length you want the finished dragonfly to be.
Step 2: using the 2 cords, tie a cobra knot
Step 3A: open barrette
Step 3: Take apart barrette
Step 4. Insert one side into the cobra you just tied. This is the most difficult part. Not the insertion part so much, but just keeping it held in there until you tie the next knot. Work this part carefully and don't get discouraged if the barrette keeps slipping out when you pull the knot tight.
Step 5A: Tie another cobra knot to secure the barrette
Step 5B: Just another angle of cobra knot tightened down on the barrette
Step 6A: tie a cobra not, but leave it loose. This will be your top wings.
Step 6B: Make sure cord goes under the little metal piece
Step 7. Tie another cobra and pull this one tight
