A Parent Hack if I ever saw one, from Melanie:
Our daughter never took to the idea of pacifiers but we tried all sorts of them and also acquired an assortment of clips for them. She is 9 months old now and we now use the clips for bagels when out and about. She likes gnawing on bagels but drops them on floor.
Here is a picture of Rose at Costco with a Trader Joe's mini bagel and a MAM pacifier keeper. I just stuff the flexible ring through the center hole and clip it on.
