The Key is to get rid of the core
Miracle Braid has a very fine diameter core line that must be removed to make a blind splice loop. Roll the very end of the line between your thumb and forefinger to loosen up the MB. Then pull it back to expose the tiny, white core--grab it with your other hand or a pair of forceps. Pull about 18" of the core out moving the braid back as you pull. Snip off the core and follow the instructions for tying a blind splice. Personally, I use a folded over piece of fine diameter wire to run up the braid, the Gudebrod tools are too light for this job. Search Youtube for "Blind Splice Loop" and select the video from Appletron. He is tying a loop to go over the end of a line, but the same thing works in MB, just leave a big loop to go over your reel.
