This is not the best video on the planet (
https://www.youtube.com/watch?v=OqMiC1_JdqQ) but it does cover a technique I previously mentioned. Using this method ( or the original paper pattern and a glue stick) ...makes less bulk, reduces mistakes, improves accuracy, no tearing away paper and when you press the seams open you have a far better chance matching those bulky intersections. I also found perforating the pattern with a tracing wheel makes folding a cinch.
