Heigh-ho, heigh ho, to work in the studio I go
It's the first time I can say with some certainty that the customer was disappointed with the end result. I even used a wallpaper smoother to get the wrinkles out, but that result in a smooth canvas. Sometimes the wrinkles happen in drying. They show up more in the photos than when you are looking at it in person.
I also finished off this one I've had papered for a while. If it doesn't sell, I can hang it going up to my office.
