The Wandtatoo summer grasses is like a puzzle. but looking at the sparse instructions carefully look at and which depends on the letters and numbers - in such numbers / letter combinations are the pieces labeled - then it can be very well put together on the wall. The abutting edges fit exactly match. Everything is very well made and adhered very well to the wall. From a short distance no one sees the abutting edges. When I again need such Wandtatoo, I would buy again from infactory.
