There is a tutorial for the flower bows on The Ribbon Retreat website. I just play aorund with ribbon sizes to make them big or small.
There is also this one that I have done as well. http://girlythingsbows.com/button_flower_clippie.html
I also have the No Bow No Go template and I can make smaller bows using them. Like the pinwheel and the twisted. I have seen people make their own templates out of cardboard and such so maybe go that route?
Would you mind posting a picture of your tuxedo bow. I have only made them with bigger ribbon and I would liek to see how they look.
