I spent an enjoyable afternoon at my craft table with the window open, and a little bit of fan action. It was 80+ outside so a bit of indoor breeze made it perfect.
I've used the stamp set Woodland Wonder from Stampin Up. I thought it would be perfect for a slimline card. It comes in 3 separate stamps for the whole tree so it can also make a great fun fold card. I also decided on a whim to add a bit of the stamping to the envelope. The sequins on the envelope are there only to obscure my address for the photograph. (Those slimlines are tough to photograph!)
