It was fairly easy. I picked up the eyelets along with the tool to install them for about 5 dollars from Michaels. I went with the smallest eyelets I could find because I figured the smaller they were the better the laces would hold. I marked where I wanted to place them with a white pencil and then I started making the holes and putting the eyelets in one by one. The hardest thing was finding something to make a hole in such a thick material. I ended up using a fat screw and literally threaded it through the pant. I did slip once and cut my finger pretty nicely. it ended up in a crookedly placed eyelet. The pants had the double belt and I never cared for the top one. It constantly slipped while the other stayed in place nicely. When I was done I just undid the threading on the top belt from the pant. Head over to Michaels or a store like it. You basically make the hole, place the eyelet, hammer it with a separate tool, done.
