I don't like this one, it's kinda ugly, but I like the idea. DIY Sweater (mini) skirt - can be as short or as long as you want, depending on the size of the sweater you use to start. Definitely want it snug though I think, so take in the sides if need be.
take a pictures of the rings on a newspaper the day of the wedding :) already married but such a great idea! this would be a great anniversary idea too. every year take a picture and make a photo album
