"Bold Gryffindor from wild moor, Fair Ravlenclaw from glen, Sweet Hufflepuff from valley broad, Shrewd Slytherin from fen." 
These were the first designs I ever created for coasters, and I admittedly was inspired by my sister. We grew up stealing the Harry Potter books from each other and going to launch days at the book store, so it is no mystery why this was the first set I created.
