How to make Spider Silk Thread

Step 4 Clean and untangle the Silk

The silk from old spider webs will inevitably have things such as leaves, twigs, dust, and most often, leftover insect parts. These will need to be cleaned out of the silk. To do this, use a pair of tweezers and extract the debris and insects, all while trying not to break any of the fibers. 

Next, in order to keep the length of the thread as even in thickness as possible, untangle the fibers and try to distribute the fibers from thicker parts of the length to the thinner parts of the length.
