A few years ago, I got mad about having to camo my blind differently every night for hunting different areas. So I bought a ten pound box of rafia grass, 300 clothes pins, and 300 small zip ties (4 inch was the smallest). The clothes pins and zip ties ran less than ten bucks at Wal-Mart. The grass was on sale at Cabela's for $20 bucks!!!
I bought Ritt clothing dye in grey and green and a few cans of spray paint for dead corn fields and beens. I then cut 10-12 inch wads of grass and zip tied them through the eye of the spring on the clothes pins.
The green and grey clothing dyes worked great and I dyed enough grass for winter wheat fields and dead old beans. The grey took longer to soak to get it dark enough. I left the green in for an hour and the grey for two hours. I hung it all to dry and then spray painted a few clusters to get some different shades.
They do sell the grasses in different colors, but it was so cheap when I bought the plain grass! Anyways, I keep the colors in different bags and camoing my blind now takes about ten minutes to clothes pin waterever color I want! then I throw a few handfulls of native stuff from the field on it. Camo-ing my blind this way lets me hunt anywhere I want to without a big hassle of tieing grasses on permanantly.... Hope this help give some ideas to anyone looking for a way to save some time during their set up!
