Here is what I do. I find an old mouse pad the think ones, and flip it on back side. Then I peel the wrap off and lay it face down on the mouse pad. Then, with a shaft, nocked preferably, I do; you line up one end of the wrap with the base of shaft where it meets arrow. Then before you start to roll, you bring the rest of the shaft parallel with the wrap, and then I begin to roll the shaft, adding a little pressure so the shaft keeps pulling pressure on the wrap as I roll it forward. You roll the shaft across till the wrap is completely on. Then I use a rag and roll the shaft around the wrap to make sure the end especially is down good. Then I fletch it! and then cut to length, put the oversert on, and then I am done!
Hope that helps and there are some pictures and instructions in most of the packages.[8D]
