This is the third book in the "Bold and Easy Coloring Pages" series. This big, bold coloring book contains 60 coloring pages, each printed on just one side of the page. This book was designed with especially dark coloring lines and bigger coloring spaces for easier coloring. It's perfect for people with vision issues, or those who have difficulty holding a coloring pencil or marker, too. And, though this book of abstract coloring designs was created for adults, it's fine for children as young as two years old, as well. There are 30 designs in this book -- two pages of each design -- featuring mandalas and kaleidoscope images. 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.
