The nice thing about these four-Schipper designs is that each image takes only about 2-3 hours time. So one must not be a picture unfinished, but can finish painting it in one piece. The Schipper colors are really very high quality, so it is not a problem every week just to paint a picture.
My four, I have divided on weekends - and by the fourth week, the colors were still as good as when you first open. When you read the accompanying advice, you have no problems with long brush four weeks. If one deals with the wrong brush, you should reorder thin replacement brush for safety.
Color coffee break images are beautiful. With a plain black or dark brown frame very classy and using a clearcoat, they see even like real small paintings)
As always - 5 stars for Schipper.
