DIY Easy Tissue Paper Flower Ball. You actually should read the tutorial for this one because the edges in step #1 are actually cut in step #4 (in the DIY not kit version). This big pom pom like ball is really cheap and easy to make. Tutorial at giftpack here. *Photo orignally from Koyal Wholesale, where these flowers come in kits 2/$10
Don't just make them for cards...how about the center of flowers, or a 3D turkey tail feather or bunny butt....so many possibilities. Use less ribbon for thicker ribbons or smaller bows. Make the size smaller by wrapping the ribbon around 2 fingers or make it huge by wrapping 4. Play around with it...easy and fun!
