I haven’t been to Swapfest since last year, and realized recently that I needed to remedy that. This is what I came home with (also a pair of pliers, but they are less exciting and photogenic):

On the left, a bag of EMF shielding; on the right, some really lovely bearings.

The shielding is stuff I have experimented with before, but I only have a small quantity left, so I now I feel free to do more experimentation, and have plenty for good results, too! It has an adhesive strip on the back, which is not particularly useful for me, I think.

I did not buy out the bearing seller’s entire supply, but I was tempted. They’re so pretty!

Some of the bearings have tiny springs in between the balls; other have more rigid spacers.
