Have you checked the dimensions on yours against ameristep blinds? I would think the windows would line up at least similarly. Could always get snow camo (or plain white) material and a needle and thread (or Red Green it together with duck tape on the back side of the seams!). Or I've heard of using fake snow spray? Heard it is not permanent, if you're wanting to use the original camo pattern later. If not, white spray paint. Definitely would need to let it air out before setting out in your spot on the last two ideas. Or if you have haybales in the area, go with a hay cover.
