Very nice book of 20 inspirational quotes to color, one on each page, single-sided on heavy-weight cardstock.--------------------------------------------------------------------------------------------------------------------------------------------------------------Most of the quotes in the book are from Gretchen Rubin but there are also quotes from Plutarch, William Morris, Robert Louis Stevenson, John Bramhall. and Montaigne. All of them are secular and positive maxims for a happier life. Each page has the hand-lettered quote and ornament - sometimes a border, sometimes a decorative element within the words, sometimes both.The pages are a very heavy-weight cardstock, heavier than the postcard coloring books I have run across, so you will be able to use almost any coloring medium with them. If you are going to use something very wet, such as watercolors, you will probably want to remove the page first and staple or tape it down to a drawing board so it will not buckle; most of the quotes have a small empty border edge so you could tape or staple them this way without getting into the coloring area, but not all of them. The pages are not bound, but hung in the book by a rubber edge, much like a memo pad, so they will be easy to remove.Once you finish a favorite quote, they are heavy enough you could lean them up on your desk or bookcase, no problem. The page size is 7" x 9" which is not a standard frame size, but if you are willing to go to the effort of matting them or mounting them on a backing board, they would work well in a 8" x 10" frame.Most of the images are not very complex, so almost anyone can color these. Although not complicated, the designs are well-proportioned and elegant. Some of the designs would work well with a colored background if you wanted to go that direction. Not all of the letters are fully outlined in all of the quotes so be careful with a dark or black blackground - the letters may 'break up' too much.If you want to have them more complex, you could try amplifying the outlines some, especially with special effects such as metallic markers.Gretchen Rubin suggests in the book approaching the coloring as meditation, to focus and rest. Also she suggests trying coloring while listening to her podcasts.
