Hi all!! I was looking through a modeling accessory Mag. and saw a sponge applicator for weathering powders. I have always applied them with a brush with O.K. results, but I end up wasting some and beating the heck out of the brush trying to get the effect I want.Anyway the sponge app. looked good but still too big for what I wanted. Being divorced I had no make-up sponges around and didn't feel like going to the store when I thought I'd fiddle around. I was pleasantly surprised with what worked out.
First, use a tube of some sort, I'm using a plastic cotton swab because the size is perfect plus super cheap.
Then take a piece of elcheapo sponge, enough to cram down the tube with plenty left on top. At first I tried an adhesive but found they all hardend the sponge. If you cram it down far enough it stays fine.
Next trim the sponge to what ever size you want. Larger for general coverage, or smaller for more precise application.
Now you can easily put a little powder in the top and rub the sponge down on the pigment. The sponge really grabs the powder well and there's no mess or wasted powder. I've even found you can custom mix different colors just by dipping the sponge in two colors and it didn't transfer one to the other container. Once the color is on the sponge you can really control the effect and size of the pigment you want.
Maybe give this a try , it's CHEAP and easy and it mkes those powders go even farther. Have fun!!!
