/cgl/ - Cosplay & EGL

Long time lurker finally buying my first bag! I was looking for some pointers/improvements before I get anything. I want to make a Severus Snape bag (don't judge he's gotten through hell and back) and there are some amazing enamel pins. i was thinking of doing a plain black board and then maybe doing baby's breath around the pins and sticking with a theme. I found one other bag so I can of gauge how much merch I'll need (though this bag appear slightly older) any good tips on how to avoid dead space? I've been trying to really think outside the box without it being tacky. Thanks y'all! (pic attached is the one I found if anyone could tell me where it was from that would be great...they've got some killer merch)
