So this is my second last general practice week, and I also had a 6pm - 3am shift with a locum doctor (basically a doctor who visits you at home after hours), and have been completely knackered. So in the spirit of sharing the crafting love I'm linking you over to Very Purple Person, who not only makes beautiful clothes but has also devised a very simple completely reversible bag with a free downloadable pattern and clear instructions.
The reversible bag took me just over an hour to complete as I added zip pockets to both sides.
If you would like to add zip pockets to your version as well I have a tutorial for them in my Soy Envelope Clutch Tutorial - about halfway down.
Ps. I may post later this weekend on how to make your own DIY fabric labels if I managed to complete my essay on time! Wish me luck.
