I have had alot of deer including mature bucks come in close to a ground blind. I like to find a low hanging tree limb and pop my blind up under it so that the branch covers the top of my blind and some of the sides if its big enough. Then brush it in like there is no tomorrow. Turkeys don't care if a blind is brushed in or not but deer definitely do. Just grab vegetation from around the blind and somehow attach it to your blind. You will really need it brushed in good to work for deer, and it might take a little bit for them to get used to it.
