I'm in the market for a starter's pastry set and I was wondering if anyone has an experience using silicone bags, which I saw on Amazon but don't seem to have any ratings or reviews. I'd really like to use something I can throw in the dishwasher, which you can't do with the canvas ones. I know many people use ziploc or disposable bags, but I try to be pretty environmentally friendly and minimize using disposable things, especially plastic. Silicone bags seem like the perfect compromise-- but not if they don't work well! Thoughts?
