Colouring for adults (lol)
I coloured Shoes by D. Palmer. It gave me a hell of a headache, especially trying to colour in itsy-bitsy details under severe sleep deprivation, but it calmed me down enough to give me 2 hours sleep.
I’ll take 2 hours sleep over none, thank you very much. But I wouldn’t recommend colouring activity for insomniac. -_-
If you fancy a bit of colouring activity, here is a huge repository of pictures you can colour in. If you prefer an adult/complex ones, grab a few from D. Palmer’s collection. :)
