To make this wonderful paper ball you have to cut a flower like template with cuts as shown in the photo. Then if you want in one flower attach a string with the help of tape. Start interlocking the flowers between each other with the help of cuts and with every six flowers make a cup shape. Make two such cups and then interlock them between each other. If you like you can use a combo of two to three colors in one paper ball. Make more in the same way and hang them or place them on table without the string. Enjoy crafting!
