Slowly but surely. There were three coats of primer. And then each color required three coats. Yesterday I removed the masking tape and touched up a few places where color had seeped under the tape. Those touchups will need two more passes. And then the whole thing will get three coats of sealer. And then, oh then, John and Justin will hang it on the outer wall of the workshop.
I don't know what folks charge for a custom painted barn quilt, but it probably isn't enough.
