When I travel during the winter months I try to prepare by taking a few creative tools to play with. Some years my suitcase is more art supplies than clothes but last year I kept it simple. I took a small sketch book/art journal, a box of watercolour paints, a few brushes, pens and a glue stick. It was very low key, without any direction except to let myself play!
These few items didn't take up a lot of room in my suitcase and provided that needed fix for creative play. When travelling, it pays to be prepared...bathing suit...check, flip flops...check, paints...check...!
