Here's a card that I made for CAS136. It might not have a lot of open white space but it has a lot of open brown space. The challenge was to have leaves on your card. My leaves are embossed on the scallop and stamped with Versamark on the right edge of the card.
I loved this sketch by Mommy Geny and used it for my card.
Thank you for looking and have a very blessed day.
