Easy styrofoam egg with the Stampin' Up! 3 flower punch. Punched a ton of these from Green Galore, Pixie Pink, Only Orange, and Yoyo Yellow, all retired SU colors. Using the little foam piercing mat I pushed down in the very center of each with this old embossing tool to curve the petals up. Remember the old days when we would actually emboss by hand with stencils and styluses?
Make sure that you use the flat end of the stylus to push all of the pins into the egg or your fingertips will be super sore.
