I know that feeling! Although, this challenge isn't talking about feeling up in the air - it is more about things that are up in the air. The obvious ones would be planes, balloons and kites - I decided to go with more natural things up in the air - clouds and moon or sun.
I am entering my card into these challenges:
Eureka Stamps - Up In The Air
Penny's Paper - Anything Goes
I used a spotted paper for the background - I think it comes from Kaisercraft. The image is from Eureka Stamps. The die is one I bought recently when my daughter and I took a week's break to recharge our energy levels. It is one from a Spellbinder set. I coloured the image in copic markers and then used Stickles - Star Dust for the clouds. I added some blue satin ribbon and bow to the lower part of the card.
