Take an old saw blade, perhaps from a hack saw or old sawz-all blade and drag it lengthwise along the broom stick. Run the teeth up and down several times in long strokes and you will lift the surface grain into a much more believable texture. You'll also remove any varnish and then you can restain them in any "natural" color you like.I have some log loads made from broom stick handles but they don't look like logs since they're too finished. I may have to try cutting them up into barrels instead. Painted flat black I think they could pass as them easier than logs.
