How to Make Spider Silk Thread : 8 Steps (with Pictures) - Instructables

Step 5: Combine Fibers. In order to combine the all the lengths of thread into two long lengths, I placed the lengths next to each other, overlapping by 2 to 3 inches on the ends, depending on how thick the fibers were. I then twisted them together in the same way that I twisted the fibers when I collected the silk.

Spider silk - Wikipedia

Spider silk is a protein fibre spun by spiders. Spiders use their silk to make webs or other structures, which function as sticky nets to catch other animals, or as nests or cocoons to protect their offspring, or to wrap up prey. They can also use their silk to suspend themselves, to float through the air, or to glide away from predators. Most spiders vary the thickness and stickiness of their silk for
