We accidentally ordered a 1500s puzzle and this mat ordered later because of any necessary mobility. One can only say - It goes like this ... Unfortunately, the document raises quite folds and you have to work carefully in mind, since the parts vershieben quickly and at worst, "say goodbye" to the bottom. Roll up the half-finished puzzle we have not even married. At the cost of the mat is but ok We have now bought us the more expensive option.
