There is a bag that sounds a lot like the one that you are looking for on "sew sweetness.com" called the Dot,Dot,Dash bag. It is a downloadable pattern for about $9.00. I also saw a similar one for free on "sew4home.com. Look in the project guide for bags and totes. It had 3 zippers if I am not mistaken. There are lots of different projects on that site. I have made several and was really pleased with most of them. Good luck finding what you want.
