I spyed a similar project in one of Martha’s special holiday issues.
I have had these molds for as long as I can remember. I just can’t remember why I have them. I think I must have felt like no well stocked gourmet kitchen should be without these molds. Alas, they have never been used.
I first painted the inside with craft glue. The glue was not sticking to the metal. I quickly switched to a spray adhesive. Which I definately recommend using outside! I sprinkled them with glitter and I love them! After adding the tealights, they just sparkled. I think they look so much grander grouped together on a cake stand.
