This is the best bag ever. Lots of pockets to keep the project organized and I can get to cash and my cell phone very easily. It is reasonable priced, too. I am giving one to a friend!
I have this bag in Turquoise, which is really more like a sky blue, and I love it. Lots of pockets to sort things in and the top of the main bag zips closed. It's not too big/not too small.
