Here's the cool tool! It's a floss threader but I used it to thread my red laces onto my skate. Here's how.
Pull your red thread through the loop so now it will act as a needle would. Pull the thread through the bottom hole back to front first and pull thread to the half way point. now pull the lace through the holes from the back as you go up. Release that thread and put the other into the threader. Now pull that thread through all the holes from the front which should create that little cross until you get to the top. Tie a knot and trim the ends.
I included a threader in each of the kits.
