I've always loved vintage Easter cards so I decided to go with that kind of theme for my tree. With that in mind, I started looking for a set of eggs with the right kind of look -- not too bright and NO PINK, thank you very much.
I replaced the birds' green and white ribbon with narrow cream satin ribbon. Then I attached the same satin ribbon to the eggs using a pin with a small round head and a bit of Glossy Accents glue to hold it in place. I let the pins/ribbon dry overnight, then the eggs were ready to hang on the tree.
