Learning how to make your own conductive material can be very useful when you want more control over the end product. This material can be as thick or as thin as you want and you will have control over the amount of conductivity. Plus, once you have the conductive fiber mixed, you can get very creative with how you use and design with the fiber. You can create simple digital and analog switches are more complex circuits.
Using hand carders to blend your wools together is a great a reliable way to ensure even distribution and control over the finished mixed grade.
I am experienced with three different ways to get your metallic wools mixed in with your fiber.
1) pulling and laying fibers, on top of one another, interchanging the metallic and pure wools to blend
2) using hand carders to blend
3) using a drum carder to blend
This tutorial goes over option 2) stay tuned for the other two!
Step 1: What you need
* Fiber - combed top that is 100% sheep's wool is the easiest and most accessible to use, however you can use other blends, batts and so on... what does top, roving and batts mean? check out this article and photos for some clarification on the differences.
* Bronze metallic wool - find bronze and other metallic wools here: lustersheen.com
* Hand carders - you can use pet brushes if you do not have hand carders or are waiting for them to ship to you. Used in these steps are kitteh brushes.
* Upholstery foam - at least 1 inch thick, can be found at any craft store.
* Dry felting needles - used here are triangular size 38 needles, good for courser fibers. check out this article for recommendations on different sizes.
* Kitchen scale - this is really helpful, but could be considered optional, I like to know how much conductivity I am putting in my **rolag... what's a rolag? more terms! This article defines it and gives still more clarity to the whole roving, batts, and top definition.
Get a digital scale that does grams.
** technically a rolag is the carded fibers blended, then rolled off the carders, Since we are not spinning, I do not actually roll them up...
