I did my delectable mountains with the large triangle and HST instead of the strip method so am not much help. I am pretty sure though that I just recently saw a good set of instructions for the strip method, so I'll relook at a few things.
Check your local PBS stations for quilting shows! We have our major Seattle station KCTS -- not so much quilting there but they also have a Creates! station further down the dial that has some, in fact Quilting Arts is going to come on at the top of the hour should I tune it in.
Saturday mornings, the Tacoma stations KBTC has a couple hours of craft programming, starting with gardening and then knitting and then starting about 10:00 about 2 hours of quilting and some sewing (Like Nancy Zieman wasn't just quilting...) Beware, it changes after lunch into car stuff!
I'm not sure how it works but I think you can log into their website and watch the live stream without any additional apps or anything.
