I saw an image of a card the other day with a colored egg on it and immediately had the idea of using some of the shaving cream backgrounds as the coloring for Easter eggs on cards.
For the first ones I drew and cut out two eggs from white cardstock. Then I filled in the void with white peel-off stickers before attaching the piece over a shaving cream background.
This one in landscape format was cut smaller to leave a wide border showing. The corners were then decorated with white sticker.
On this portrait orientation I added white sticker borders to the two sides of the card.
This one also got a silver peel-off sentiment.
