Me being me, I also like making things.
This is what separates success from the mundane. By that I mean: the ones who "customize" their gear will get results they want. Those who don't get results they must settle with.
Use everything from cellophane wrappers in front of a lens (to soften an image) to a styrofoam cup in front of a flash unit (to soften the flash harshness).
Be inventive.
