This bright color makes fabulous color accents for cards. If you apply them to a finished card, it is best to let your card dry overnight before mailing. I have begun to make different sizes and let them dry on a craft surface. I then keep them in a small jar and take out as many as needed and apply them with Multi Matte Medium. (It saves the wait for drying time.)
I chose blue to match the sky. Use these for ornaments for Christmas on crafts or anything else you want to add a little something special.
A little or a lot can come out. No special adapter tip needed.
