For one of mine, I put ribbon on top of ribbon to get the look I wanted. Love it!
Whether using a tip or not, you can start the ribbon on the reverse side by a few inches like this:
so that you will have the same ribbon showing when you have the belt "buckled" as you can see below.
I started this project with the idea of just using d-ring and only used the square ones on the black belt because I didn't have any black d-rings. I found I kind of like the square rings better because of the straight line it gives rather than the slightly scrunched effect of the d-rings.
These would make great kid's gifts for both boys and girls. With girls you get to make some fancy hair bows to match. Did I say I had too much ribbon? What was I thinking! I may not have enough.
