So for this card, I wanted to do something a bit more modern to fit with their personalities, so I thought diagonal across the bottom would work perfectly. (If you see my other post, I used these same egg dies to do a horizontal border on another card.)
First, I embossed Happy Easter from the KIS: Easter Mini set onto black cardstock. Then, I attached the eggs along the back of the black paper using VERY STRONG adhesive. Then, using scissors trim the excess off.
