Start with the 2.5" ribbon and measure a 12" tail, set the tail to thee bottom. Twist the ribbon at the 12" mark and add the twist to the bow maker. Make a 7" loop on one side, twist the ribbon, then add it to the bow maker. Repeat on the other side then trim a short tail, about 4-5", set this tail to the top.
Next, repeat the same process with the first 1.5" ribbon making your loops slightly smaller this time.
Repeat the same process with the other 1.5" ribbon. Then repeat each layer in the same order. Then make one little loop with two tails using a 1.5" ribbon, this will be 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.
