This mini tutorial comes to you thanks to Becky Stern! While Becky was working on her iPhone gloves tutorial, she came over and asked if we had any conductive thread. Luckily, we had a bunch of cone samples of thread and yarn. The good news is we had tons of thread, the bad news is that they were in 1 lb cones and Becky wanted to sell small amounts.
She had previously used a 'card' such as used for embroidery floss, but it takes a long time to wind those by hand and she wanted to get these made quick! Thats when she realized that you can buy a bobbin winding machine and pick up plastic bobbins from any sewing shop.
