Grid or decorative

There are two kinds of waffle irons: rectangular grid waffle irons and rectangular or round rimless flat irons which make paper-thin wafers, often engraved with a coat of arms, family and heraldic crests, city crests, mottos, wishes and biblical scenes, but also the names of a couple often in combination with a date and hearts, flowers, the tree of life11 and even windmills (on a Low Countries iron from the 18th century).
