Trying to picture how to do this on such a grand scale
Thanks BB1,
I start at one end and with 4 or 5" pieces of tape, I hold the joint tight and stitch across the joint, then apply a long piece along the seam. I do this in about 16 -24" sections. After going the full length of the joint I will run long pieces of tape all the way down the seam (over the previously sectioned pieces).  Then I  apply a couple of more pieces offset from the first piece but still covering the seam.
I don't always use 3 lengths,  depends on what I'm doing. 2 is enough for most stuff.
Here is an example,  visual is so much easier for me to show. (love sketchup)


Figuring out how to do something you have never done is what makes a good challenge.
