Ephemera is . . . well, read the card to find out. We all have some; in fact, most of us have more than we need. So a great way to get rid of it is to make it into cards. This was part of a series of 10 cards I made from bits-and-bobs laying around the house.
As you can probably tell, I misspelled ephemeron (the singular form of ephemera) and had to correct it with a little pasted on tag. One of the reasons I love paper-crafting is that it is so forgiving.
