I used the white on white layering approach, which I love but rarely remember to use. The strawberries were colored with markers then stamped using a Stamp-a-ma-jig. I wanted a plain font for my sentiment so dug around until I found A Little Birthday Cheer.
Thanks for looking.
Edited to add: This was chosen as a top pick this week over at Hand Stamped Sentiments. Thanks!
