I used a white cardstock and embossed little bubbles on it. I did the bubbles the 'old fashion' way (to some maybe), I used a embossing template and a handheld embossing tool. My hand did start to cramp up on me! But it was worth it. I stamped on my saying and my little duck. Which the duck I stamped again on to white cardstock. Cut it out and gave it a foam square on the back and put it over my other stamped duck.
Supplies: white cardstock, green paper (ek success), embossing template (fiskars), embossing tool (fiskars), inks (black & mint both by colorbox), stamps (older clear stamps I had, any of your choice will do).
