get some sort of little bottle and fill it with unscented foot powder or talcum powder, somethign liek that and presto, give it a squeeze and you have a windchecker. I actually bought HS scents windchecker bottle and have kept refilling that one with talcum powder .
Corn starch would be a better choice , most talcum powders contain some perfume .
Milkweed seeds are ideal for checking the wind downrange , they're easy to see and you can even add a small amount of attractant scent to them before releasing them .
