basing materials
Well, I haven\'t done any extremely elaborate bases yet, but I have accumulated some stuff to do it.
Go out in the yard, or out to the nearest woods, and grab a handful of something that looks the right scale. When I was in Florida I picked up some of the finest sand I\'d ever seen, just from the ground (which I later washed).
Hubby says sandblasting medium comes in various grits, is already washed, and is a neutral color. It comes in larger quantities than you\'ll probably use, but it is widely available at home improvement stores and hardware stores.
For shrubbery, I found some of the neatest looking lichen in Florida, too. It grows in little balls about an inch or two in diameter, and it has a very loose hold on the ground. I picked up a few bits of it, washed it (it gets very soft and flexible in water), and it\'s now awaiting use in a plastic container.
If you\'ve got a beach of any kind anywhere near you, you might be able to find similar materials out in the wild. Be conservative when you pick stuff up, though. If we all went around grabbing enough for the next 100 years of bases, we\'d be pretty rough on the environment (discounting completely the nasty solvents in spraypaint and the unnatural chemicals in the cleansers we use).
Take a look at the fallen wood in your area. I dunno if everyone had the same damage we did, but the storm that came through right before Thanksgiving really knocked down a lot of nice limbs and sticks. Dry them out good in the sunshine and seal them up in a plastic bag after to kill the little critters.
You don\'t have to buy static grass and gravel--it might be quicker but it will be more expensive than walking around the neighborhood. Take a mini with you to stand next to the stuff you plan to grab to make sure it\'s going to fit the scale.
I use a regular plastic painter\'s palette from the art store. I have a big box of toothpicks for mixing and moving paint from the bottle to the palette. I use parchment paper (the kind you cook with) as a working surface, since I can get the painted toothpicks back off it without any trouble. I use those simple clear fishing tackle boxes stuffed with wadded cotton or polyester fluff as containers for my minis so they don\'t get damaged. I keep my set of GW paint bottles in more of the same tackle boxes to keep them upright.
A good lamp is essential. I\'ve got one of those ott-lite desk lamps with the flexible arm, and those are the good stuff, man. I can\'t get over how much better you can see with one of those, even though I was sitting next to a bright window while I painted, the ott-lite shows up stuff I just couldn\'t see before.
Anyway, look at the stuff you already have. Kitty litter and fish tank rocks might serve in a pinch as boulders or rubble. A bit of bark mulch from the bushes might be an interesting overhanging cliff-type rock. Someone else posted about herbs as organic material. Dryer lint and glue gives you a sculpting medium with a semi-rough texture. So does flour and glue for that matter.
Making bases on a budget means you can get creative. You don\'t necessarily have to spend new money on fancy stuff.
