Scripture Doodle is a six-week Devotional that teaches coloring techniques. They are written by author April Knight. I received both books to use for inspirational devotions. There are coloring activities, prayer appointments and more. There are 120 pages in each book, enough to keep an adult busy. Yet more if a page seems difficult. Just work at your own pace and relax. It's set up to do a page a day, so depending on your pace the devotional could take longer. Once colored the pictures are worth framing.
These books can be fun for older teens and adults. There is also information about basic materials used and coloring tips, so even the most reluctant can enjoy art. All the required supplies can be found at your local craft store.
