Ken, I haven't put it on yet. Still waiting on the controllers! I ordered my first ones from ebay but they didn't perform as the specs said they should. I could barely feel heat from them for my gloves so I just boxed 'em up and sent 'em back. Gonna try again with a higher output controller. Once I get the controllers, I can use the stitch witchery to "sew" the shirt to the fleece over the wires. I'm not going bother to sew the wires to the fleece. Want to wait to see if the 30 ft of single stranded teflon wire will produce enough heat or if I need to add more feet in the front. I can't decide which is more fun, making the heated gear or making the controllers. Both is a challenge! I'm even going to make a vest for my "motohubby". (If he were the real deal, I'd do the full monty!) Too bad I can't make a little extra cash doing this, I'm going to have LOTs of wire leftover.
