I made my first index-card-a-day and finished this cover. The button is from my grandmas stash and the elastic cord is just wrapped around the stack of cards right now. 
The rest of the day has been spent with really bad side effects. I've never had such bad ones before... I finally took a painkiller and went to bed. I'm almost afraid to move as it is now and I'll be staying home tomorrow. Can't do anything with those side effects...
