Even though the outer layer of wool yarn is completely and intentionally knotted, the composite yarn is still extremely flexible. Also, while the outer wrapping should be relatively tight, one can still squeeze between the loops to electrically connect to the copper core if needed.

After confirming with Prof. Buechley that I did not have to make 2 yards of the wrapped yarn (as long as I had constructed 2 yards of the individual yarn components), I decided to make my electrically insulated yarn. I'm very pleased with the final composite yarn, though I could significantly improve my wool-spinning technique! The wool yarn was initially too thick and had too much variation along its length due to my poor technique, so I definitely hope to have more chances to improve my skills. In terms of creating the copper "yarn", I was very pleased with how easily the copper fibers would "stick" to each other, making it very easy for me to create a long piece yarn.

After experimenting a bit with my plastic fibers, I realized that I could not easily create the type of spun yarn that I wanted to, so I decided to ditch the idea (for now) and to create an electrically insulated yarn made from textiles. In fact, when the yarn assignment was announced, I immediately thought about making an electrically insulated yarn, but it was not obvious to me how I could spin this type of composite yarn. I thought about dipping an electrically conductive yarn in a curable flexible polymer like silicone or wrapping the yarn in a non-conductive yarn (as I have shown here). However, I thought that wrapping 2 meters of yarn would be a really tedious task!

I initially wanted to make spun "yarn" out of plastic grocery bags and cellophane strips/"fibers," and to crochet a new bag out of this new yarn. I could have easily crocheted something out of strips of plastic bags, but I wanted to create spun yarn, so I attempted to create a multi-ply yarn by "spinning" twisted grocery bag and cellophane strips together. The purpose of the cellophane would have been to help hold the yarn together, as it generally has nice adhesion properties.

The wool yarn that was to be wrapped around the copper yarn was constructed via spinning. Below are two sets of images of my two attempts at spinning wool yarn. The yarn from my first attempt was too thick (the diameter was too large) for working with when I tried to wrap it around the copper wire. Therefore, in my second attempt at spinning, I took portions of the first yarn to re-spin a thinner yarn.

Note: This method of wrapping the outer yarn and making consecutive knots to create a spiral pattern is common in "friendship bracelets" as well as hair wraps.

Below are images of my final composite yarn that has an inner layer and an outer one: the inner layer is copper yarn made from copper fibers rolled together, and the outer layer is made of yarn spun from wool fibers. In order to completely cover the copper yarn--and thereby electrically insulating it--I wrapped the wool yarn around the copper yarn and made consecutive knots with it along the length of the copper yarn. Note: This form of wrapping the outer yarn and making consecutive knots is common in "friendship bracelets" as well as hair wraps.
