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)
