Make an Angel Card
Collect pictures, bows, lace, flowers, colored paper, and anything else that speaks to you. Get some glue and colored pens and make an angel card. You could use an image of a specific angel from a book or draw your own. You can write a letter on the back of the image or use it as a focal point for your altar.
There are also many wonderful angel decks out there. You could make a series of angel cards that highlight different attributes you would like to have such as abundance, patience, laughter, joy, gratitude, or courage.
