I do mine by hand, what size in inches are you looking to make with the 2.25" ribbon? looks like maybe a 7" bow?
For an 6" Twisted boutique cut ribbon 42 inches long. Make a mark at 3", then make a mark every 9 inches. If you want it bigger increase your marks by .5 or 1" increments. The example picture has a really long tail so you'd probably want a 5" tail for that side.
