Here's a fun, easy Ribbon Bracelet I made recently using twill ribbon that looks like a tape measure. I measured my wrist (about 6"), then doubled that (since the ribbon loops back on itself) and added about an extra 3" (to allow for hemming and the overlap of the loop).
To start, I folded the ribbon in half and zig-zagged all the way from the tails to within about 1/2" from the top of the loop. You want this opening to be big enough to snugly go around a button since this will be the bracelet's clasp. And don't be stingy with the zig-zagging up here...it should be good and sturdy.
I sewed on the buttons with regular old black thread, starting with the button furthest from the loop (in this case the round wooden one on the far right), dinking around with the placement to make sure that when it went through the loop, the bracelet would be snug but comfortable. I trimmed the tails so that I could turn under about 1/2" and zig-zagged the hem.
Then I sewed the rest of the buttons on, layering some of them (the spacing was a cinch given that I was essentially sewing on a fabric ruler) and Presto! I had a fun bracelet using only materials I already had on hand.
