Do you have a clever trick for dressing children's shoelaces?
My son loosely ties tennis shoe laces such that they always fray even after I put glue on the ends, melt them, or knot the ends.
Here is a picture of his shoes that I'm dealing with now:
New shoelaces aren't necessarily the best answer because they too will fray. Neither is simply scissoring the ends (it's not repeatable).
What I need is a repeatably cheap method to prevent fraying and to harden the tips for lacing that can be applied at home as a DIY to make my child's sneaker shoelaces last longer.
Do you have a clever idea for inexpensively repeatedly dressing shoelace ends that you can share with the world?
