I made these flower bud vase holders awhile back so my husband could give them to some ladies who were very helpful at work:

Someone here on the board made some, too, and very kindly sent me a picture. You can get the tubes from Amazon for a reasonable price. It uses up scraps, too, which is always a plus in my book!
