before you go about rattle canning your blind you might try this trick I use to revive faded camo clothing. it wont revive the camo back to original but will darken the faded colors enough to make the camo useable.

take the fabric skin of the blind and wash in cold water with no detergent but add some black fabric dye but not too much maybe one or two dye tablets. then rinse twice with cold water allow it to dry completely. if its not darkened enough for ya repeat the treatment untill its darkened enough. good luck
