I really wanted to make something celebratory for spring. This is huge but only took me a couple of hours to make. I chose paper scraps in a pretty color scheme and a couple of metal rings that are usually used for wreath making.
Punch a bunch of paper dots with a paper puncher. Sew dots together into a very long garland, leaving some space in between each dot. Connect 2 different sizes of metal rings by tying string between them at 3 places Tie 3 strings to the outer metal ring and tie them in a knot a 1/2 yard above the ring to make a hanging arrangement. Cut your garland into shorter pieces and hang over both metal rings. Make the inner end a little longer and the outer a little shorter. Secure the garlands to the metal rings with a little bit of hot glue. This will make your mobile more stable.
