Just get or make some shooting sticks. I have a set I made a while back out of 5/8" wooden dowel rods, bolt, washer, and lock nuts. I have a camo handkerchief that I wrap around the cross point to avoid damaging wood finishes. I wrap it in kind of a double figure 8 after folding it several times like you would do for a bandanna. I get it wrapped on one stick then go to the other one and then back till I have no handkerchief left, then tie it off. It keeps the sticks open and ready for use.
