To begin, it is important to understand the basics of seahorses. Seahorses are a type of bony fish, which classifies them in the animal kingdom, phylum Chordata, and class, Osteichthyes. Seahorses are part of the family Syngnathidae, which also includes pipefish and sea dragons (Boschung 530 and Moore 1).
Fat Quarter Bundles. Fat Quarter Bundles are collections of fat quarters from a fabric line. Fat Quarters are quarter-yard cuts of fabric cut wide (hence the name fat). Their approximate size is 18 x 21.
Sometimes a quarter sheet size is the horse's equivalent stable blanket size. The quarter sheet described above would fit a horse that would wear a size 78 blanket (197 cm) so sometimes the sheet is referred to as a 78, but it is not 78 or 197 cm long. All of this varies greatly with sheet design, country of origin, and the manufacturer.
