This big, bold coloring book contains 50 coloring pages designed with darker coloring lines and bigger coloring spaces. It's ideal for anyone who wants an easier coloring book. This book is perfect for people with vision issues, or difficulty holding a coloring pencil or marker, too. And, this book of abstract coloring designs is fine for children. There are 25 designs in this book -- two pages of each design -- featuring mandalas, kaleidoscope images, and repeating patterns. If you make a mistake on one page, it's easy to turn the page and get an instant "second chance." (It's also an opportunity to try different colors than the first one you colored.) All of these coloring pages are based on the hand-drawn artwork of the author, artist Aisling D'Art. They weren't computer generated or mass-produced. Many are in an authentic 1960s style and feature rounded corners and geometric designs reminiscent of the "Magical Mystery Tour" album artwork, and other icons of the hippie era. If you -- or someone you know -- will enjoy coloring pages with bold lines and larger coloring areas, this book may be what you need.
