This is such a wonderful set of prayer cards! Physically the cards are very sturdy. They have stood up to the love of my 5yo, 3yo and 6mo and are still going strong. The cards are the perfect size for little hands. The art work is colorful, fun and appealing to both children and adults. I love the prayers on the back. My husband and I use them with our children, together as a couple and individually. The prayers are short enough for the little ones to stay focused and engaged- but offer enough depth to help my husband and I in our own prayer lives. The biggest impact these cards have had on our family is in how much more interested my family is in learning about the saints and their lives. My children are constantly pulling out the cards and rifling through them until they find a picture that interests them, then they ask all manner of questions about the Saints, their lives, their patronage, etc. Overall this is a highly recommended set- especially for families.
