Paint by Sticker Kids is unstoppable! The series ships over a million copies a year, and the reasons are obvious: stickers, stickers, and more stickers, plus an activity that delivers hours of screen-free, mess-free fun. These days, rainbows are about as hot as stickers—Rainbows Everywhere! combines both for pages of brightly colored joy. Each image—a sweet cat, kites flying in the air, a unicorn, and, of course, a rainbow—is swathed in vibrant hues. The colorful images use low-poly art, a computer style that creates 3-D images out of polygon shapes.
