How to Upcycle a Cotton Doily

In charity shops you can often see a pile of doilies languishing unappreciated in with the linens, it's a shame as obviously a lot of time and effort went into hand crocheting these cotton doillies. Pondering their plight I had the idea of up-cycleing them into jug/bowl covers, to keep flies off food and drink in summer. All you do to give them a new lease of life is attach, by sewing, glass beads* around the edge.
