I absolutely love this! Its something I like to do when I'm on my travels. Especially if I am sat on a boring train journey. Documenting the things you see zooming past the window can turn into new illustrations or repeat patterns. When I go to new places (especially abroad) I tend to hoard things like tickets and maps. I intend on getting my piste map framed from my recent trip to the alps! Hopefully I'll come home with lots of new ideas from my latest holiday :)
I originally found this on 'Brandy Waterfall's' Pinterest board which was pinned via Table Tonic. I've done some googling and have not been able to find the original author so if you know please let me know so that I can give them credit!
