You guys are always so helpful that I'm hoping you can help me. I want to make my first bag and I have all the fabrics but I didn't buy the rubber type grommets that I saw on the sample at my LQS because I had picked up a few packages from Goodwill for only $1. Now that I look at them I see mine are plastic and the others were rubber. Do you think it's ok to use the plastic ones or will they break? I didn't mention my cheaper ones at the shop but the gal suggested using only one layer of fusible fleece instead of 2. Any advice that can help me? Should I use the plastic ones or should I spend the $12 for the rubber ones. I am making 3 bags so the cost is quite substantial. Thanks.
