So, I headed up to the Superior north shore for some vacation time and while walking the "sandy beaches" I found some great basing material.
Ron, over at From the Warp had written a few articles and references a bunch of great resources for basing models. Something he mentioned was the ability to use natural items that are easily found instead of buying some more expensive ones. Which is words to live by, especially in this expensive hobby!
But this sand/rock just screamed "basing material"! But I found everything from small/mid size rock for sandy basing material to rocks for my models to be put with.
Share some of the basing materials you have used!
