- cardboard cut to 5 3/4 x 4 1/2 inches
- a holy card of Mary or a coloring page shrunk to 3 1/2 by 5 inches
- crayons or colored pencils if you aren't using a holy card
- popsicle sticks
- glue stick
- tacky glue
- aquarium gravel in colors of your choice
I use the Mary grotto that you see in the first picture on the prayer table in my kindergarten religious education class. To make it stand nicely, I glued the back of a 2x3 picture frame on to the back of the grotto. If you want to use this craft to encourage your child/students to learn a specific marian prayer such as the Hail Mary, Memorare, or Hail Holy Queen, you could glue it to the back of the grotto.
For around $12 I was able to get enough gravel and popsicle sticks to make close to 75 of these grottos. I was able to find store brand tacky glue for $.79 a bottle. One bottle is enough to cover 8 to 10 grottos.
You could also use this grotto set up to make the stations of the cross during Lent. I may give that craft idea a whirl in March or April.
