The lace on my Merrell Pulsates broke.
Good thing I have a bin of parachute cord at my disposal. I had a choice of brown or desert camo. Went with the latter.
I have no way of adding an aglet (what the little thing at the end of your laces is called - there to help get the lace through the eyelets and prevents the cotton most cheap laces are made from from unravelling.)
I put a button knot on the end. My main interest was in preventing it from pulling back through the eyelet.
Crafty and jazzes them up a little bit.
