"D" rings are some times called "lacing rings" and offer a decorartive alternative to setting eyelets or grommets. D rings can be stitched on by hand, but the most secure way to attach them is to use a rivet. Rivets and "d rings" are available in matching colours or you can mix the colours as they are sold separately.
Rivets can be decorative or used to secure "d-rings" for lacing. Rivets consist of two parts; a post and a cap. #79-9630 is considered a "double cap" rivet because the "post" has no divet in the bottom; the bottom of the post looks just like the top of the "cap". Always test the rivets on scrap layers that are identical to the layers of your project - rivets have a predetermined set depth and they may nt set flush with your top layer of fabric.
