I used MDF wood and cut to size. This measure approximately 8.6" x 5.7". It can be resized to make larger just be careful going smaller as it will change the cactus. You can also change mommy to daddy, grandma or any name you prefer to use. These are the cactus i use and under each cactus I engrave a child's name up to 6 children names. So display from 1 name up to 6 names. I also use clear gorilla glue to adhere each piece onto the mdf wood.
