Step 3: Sew the Board In
I carefully snipped some of the threads holding the hem of the glove down, in the back, until I had just enough of a hole to slip the circuit board and battery inside. I snipped a tiny hole right at the hem and stitched around it by hand using buttonhole stitch, for the battery charger. I placed this by feel, letting the wire go wherever, and sewed the charger down with a lot of thread wrapped around it. The circuit board and battery actually got caught a little on the knit fibers, and did not need to be sewn in place (this was lucky because later I had to take them out to fix a solder joint I'd broken).
