I always start at the top and cross lace to the bottom and then tye it off with a knot....
The bottom is laced with it's own lace....
To lace without twisting is a chore, go slow and watch what your doing....If ya get a twist, befor ya pull it snug counter twist it untill no twist and then pull snug....
I forgot one nice little detail, When you lace up the tube, you want to start the lace so end up with the last lace going into the tube, So when ya tye it off the knot is on the inside....
