Do you sometimes feel like your die-cut sentiments don't stand out enough on your cards?
Try adding a black or darker shade of the same die-cut behind it! Glue it to the back of your sentiment by slightly offsetting it to create that shadow effect.
I have used Stampin' Up! Bella & Friends puppy, Birthday Blooms flower, Stampendous butterfly, Heart Balloon unknown. Stampin' Up! Thinlits - Happy Birthday, assorted sequins and ink pads.
Why not try a bright colour underneath, would look great on kids birthday cards! Experiment and have fun!
