Floating Flower Tip - Most flowers float pretty well on their own until they start to pool with water and slowly sink. For a longer lasting centerpiece, use bubble wrap to make little skirts for your flowers.
Sew top of jeans onto skirt material. I used an old pair of jeans & an old skirt. Its so much easier with an old skirt just make sure you get the hemline correct before you sew it together. (BW) perfect for those too short girls skirts too!
