I did manage to get three of the four border strips on before an electrical incident caused a work stoppage. While preparing to press this second border, the iron began to make loud popping/clicking noises that even drew the cat's attention. In fact, Mini gazing upward at the iron was what made me notice the smoke coming out of the steam vent! The iron had shut itself off but the smoke was alarming and I quickly unplugged it and took it outside onto the concrete patio, afraid that flames would begin pouring out. But they didn't. I checked on it numerous times for 10-20 minutes and it cooled off by then so I could go to bed without worry. Scary moments, though! Tonight I plan to get the final border strip on and begin piecing the backing. I have a cheap backup iron that will work just fine :).
