I work in a school, so every May/June, I get a lot of graduation open house invites. This card is one of my favorites to use. I try to keep them on hand just in case. I made a few more so I wouldn't be so rushed in May. At least, I am ahead on something.
I am using the card for the C.R.A.F.T.'s challenge. It is a hard card to mail because every thing gets flattened, but it is perfect for the local parties every year.
