to make a simple ribbon belt you'll need:
- ribbon (grosgrain works best for me, but experiment and find what you like)
- sewing machine/needle & thread
- optional: fray check or lighter
determine the length you want the belt to be (I made Leo's 24" long), double it, and add 3/4". cut to size and melt the ends of the ribbon if it's synthetic, or glue them if it's natural fibers to keep them from fraying.
overlap the D-rings by 1/2" and sew across. with the other end, fold in half and overlap the end you just sewed by 1/4" and sew across really well.
sew from the end with the d-rings all the way down to the other end. turn and sew across the folded edge, then turn again and sew back up the other side to the d-ring end. turn again and sew across to where you started from, back stitch to secure your stitches, and that's it!
