I Use Crown Royal Drawstring Bags!
I found the medium sized 750ml works well as an all around size. There are other sizes available. Most are blue bags but there's orange as well. These were popular as marble bags when i was growing-up. I found eBay has a good selection of these bags. I also use them for separating my lead bank weights as well. Your reel's finish won't get scratched storing you're rigs or transporting them as well.
