Last year (I think, could've been two years ago) someone on the forum posted a thread about how he used an old camp chair, a couple driveway markers, and four metal binder clips, and a piece of scrap cardboard to make a target stand. As I had a couple old camp chairs I couldn't use as chairs anymore, I gave it a try.
It works pretty well, and costs almost nothing. The driveway stakes, which I think are called snow pole driveway markers cost $2/piece at Home D. and the clips are $3/4 pc. set. I don't count the chairs, as I've had them for almost ten years, so the $15 that they cost brand new cancels considering how long I used them before the seats fell out of them.
I guess they cost a tad more now, as my brother's son somehow managed to hit one of the clips over turkey day, and blew the driveway stake to bits in the process.
I was going to try to explain exactly how to make one, but I found the thread. Just search: DIY portable target stand by RolandD.
Roland took the back of the chair off, but I'm kinda lazy about stuff like this, so I just left mine on, and just drilled through the nylon into the plastic caps of the chair, so I could insert the driveway marker poles.
