Used 1 panel in light brown for a bedroom office makeover nook. It helped create a space within my room. A few notes 

1. The wood panels come on thick black felt which extends over on one side and is flush on the other side, so multiple panel pieces can overlap  fit together. 
2. Measure twice, cut once to fit. We used a jig saw and it was simple. 
3. Use black screws to install into wall (screws not included in order. Black screws will blend right in.)
4. Instructions say 15 screws are needed. We used 9. It’s fine. (We are not hanging anything on the panel so fewer screws worked in our project) 
5. Cut extra hangover felt with exacto knife to trim off if using one panel. See photo. 

Good luck!
