If anyone is wondering whether the whole 'illustrating your purchases' thing actually works... well, it does. Since taking a break from it (due to overwhelming uni work load) I have been a bit more frivolous in my spending. Soooo... as a compromise, I will be doing daily illustrations, but they are just going to be mini sketches! Roughs! (i.e, not my best work, but better than nothing!).
These were done on the train on the way home today in my new Moleskine journal (pictured below!). I think the lady sitting next to me thought I was a little weird.
