2011 Thing a Week - Week 26 - Produce Bags

This week Tara and I got together to make some produce bags. We use reusable bags in our shopping, but we didn't have anything to use for produce. Tara brought over her two kids and some tulle, and we went about making some bags.

The one with the thicker band is super cute, but I don't want to have to pay extra for produce because of my bag. The one with a thinner band works just as well but is lighter.
After one trip to the farmer's market the tulle already snagged. I read up on produce bags, and heard about some heavier duty mesh that you can get at fabric stores, so I will need to hunt down some of that. I may also ditch the fabric band all together, even though it's cute, to keep the bag as light as possible.
Has anyone used reusable produce bags at the grocery store? Will they give you a discount like they do when you have reusable grocery bags?
