That is such a cute way of closing a bag. I see a country-wide stampede to find Dritz curtain grommets so I'll pass on some of my "stampede research." (I hit the computer before I jump in the car and drive off in every direction.) Amazon has them through a Marketplace seller but the best I found is at Hancock Fabrics where you can use a 40% off coupon. (Our Hancock's honors competitors' coupons, Joann's, Michaels, etc.)
