Until I actually set out to make these, I'm going to guess that the supplies used are the 2 1/2" Circle Punch, Sweet Treat cups, Whisper White cardstock and the Large Oval Punch. A few white mini pom-poms, which you can pick up at your local Dollar store or craft store; and some pastel candies (m&m's in this case), complete the ensemble.
In the meanwhile, I did come up with this cute card for card club not too long ago. The card features Eggstra Spectacular from the Occasions Catalog. This adorable little set can be used in so many ways. I can't wait to play with it some more. I'm thinking an easter egg tree using the egg stamp might be cute. Check back for my blog post on that creation!
