Popup blinds are pretty cheap these days, but they can be noisy to set up and require a lot of brushing in to conceal. A very nice portable (and cheap) blind that sets up quietly can be made of 54" camo burlap stapled to 54" 1x2 poles. Drill holes in the ends of the poles and then drive in extra long pole barn spikes. Then cut off the heads of the spikes. The spikes stick in the ground. Cut out a shooting hole that will face your trail that you hunt. Bring along your own pine or spruce branches to brush this blind in. If you set up among some spruce trees and brush in, you will be virtually invisible and the blind itself will help contain some of your scent. I use this type of blind on public land quite a bit.

On public land you can (usually) legally construct a permanent blind of natural materials that have been gathered (no cutting of trees or branches). That said, you might want to just partially construct some blinds and then when you hunt, finish by attaching camo burlap lined around the inside. By only partially constructing, you will not be giving away your hunting spot locations so easily.

From a blind, be extra diligent in scent control. You can, however, successfully hunt this way. And it is kind of exciting to be on ground level so close to the deer. To draw back in a blind, set up so you can draw back to the side of your shooting opening and then ease into the shooting window.
