I used the tube method to make a bargello wall hanging using 12 strips at a workshop. I found lining up the seams on the tube to be a right old pain in the you-know-what. I pinned mine to make sure the strips didn't shift when cutting; but if I was making one again, I would use smaller strip sets and join in the end, it would be quicker. Many of the others in the workshop gave up and switched to strip set.
