Colouring books for adults are a trend right now, but an enjoyable one. It’s relaxing to just sit and colour (though you really need to get the good pencil crayons, mine are so cheap they don’t work very well). A lot of libraries are starting to run colouring parties for adults, with the idea that it’s creative, relaxing, and a good way to socialize while you’re asking someone to please pass the blue crayon. This link is more for throwing a personal party, but it can be easily adapted to a library. You can get easy colouring books with large, simple designs to colour, or books with more intricate patterns that require more attention to detail. Crayons, pencil crayons, markers, you can use any medium you choose. It’s simple, cheap, and fun–the perfect program!
