First time use of these panels. I chose them because of the length and color. Other vendors had half the length. 

I recommend panels. Used liquid nail glue and nail gun to apply. Used razor blade to cut black felt  jigsaw to cut wood. Got navy paint to cover cut panels. Used paint pen  to cover nail heads. Takes 2 people to install. 
Ordered 6 sets for the 9 foot tall x 12 feet wide wall. .Removed baseboard to make it fit.
