22 Days 'til BEA: Indecision! Flap or No Flap?

I made this bag and and was about to put a flap on it when indecision set in. Flap or no flap?
It needs a closure, so maybe place the flap inside? Or use a magnetic snap closure along the top edge without a flap?
Flap, flap, flap, frickin' flap! To flap or not to flap: that is the question. I flap, therefore I am??
I'm going to take a break and return to this bag in the morning. Good night!
