Start with the 4" ribbon, measure a 12" tail, twist the ribbon and then add it to the bow maker. Then make 2 7" loops, twisting the ribbon after each one and adding them to the bow maker. Measure about a 5" tail and trim the ribbon from the spool.
Take your first 2.5" ribbon and repeat the same process making your loops smaller this time. Then use the next 2.5" ribbon to do the same thing.
Grab one of your 1.5" ribbons and repeat the same process, making the loops smaller again. Now work through each of the remaining 1.5" ribbons, making the loops smaller each time. With the last 1.5" ribbon make one small loop for the center of the bow.
Take two pipe cleaners and twist the ends together to make one long pipe cleaner. Remove your bow from the bow maker and use the long pipe cleaner to secure the center of the bow twisting it off at the back.
