I've got a quick Thank You card for you today. I used paper from GCD Studios' Ella Blue collection and a K & Co. butterfly embellie.
One trick I like to do to use white space is to create a "block-style" sentiment. The "thank you" stamp is from PaperTrey Ink and I inked it up and then stamped it twice before inking it again. It results in a really interesting variation in the stamped words. I just stamped it one after another (even running off the card) so that it would filll the space that wasn't covered by patterned paper.
See? Super easy.
Have a great afternoon!
