This door pull for barn door is my favorite.
I like this type of rail for the barn doors - stainless steel to complement other modern chrome touches (e.g. the fans, kitchen hardware, etc.) It will need to be strong enough to smoothly carry two big 7' tall x 30" wide door panels including mounted art work.
Another possibility, if strong enough.
STOP HERE! The photos following are just inspiration and FYI for future jobs.
Example of barn doors. The background behind the paintings (to be on doors) will need to be white to match the living room paint. It needs to basically look like a wall panels with the paintings "hung" on top.
