I have an older Avery Power Hunter that I haven't used in years, so might as well sell it. I put velco over the velco on the blind and tried magnets that didn't work too well, you can see in the video and the seams started to rip, so I added a patch and glued them, but the rest of the blind is good shape. I bet it hasn't been used 10 times.

Let me know if you have any questions.
