Scraps left over tend to make interesting cards. Adding banners, or bits and pieces can add dimension and texture to cards. Also, tags can be a way to pop out your sentiment. This card, layout found here, uses both a tag sentiment and scraps as ribbons, even my favorite Shimmer Trim.
Layering the different scraps, stamping bits, even adding doodads like Badge Buttons, sequins, and fibers, make cards more interesting. The above card has everything. Using a sketch from LilyBean Paperie, I stamped on B&T paper, cutouts from the Cricut, Badge Buttons, and different ribbons. This card has a lot going on, but I love how it makes the eye travel is so many different directions.
