I think I'd stay away from the nylon-polyester blend for something you intend to wear around your neck. I suspect it would feel sweaty in summer, clammy in winter. If you're going to use a ribbon with nylon content, I'd look for one that's blended with some natural fiber.
Silk or rayon, or blends of rayon with cotton -- now that's another story.
They're soft, drapey and breathable. Unfortunately, they're pricier, too.
I made a drop-stitch jacket with Piadina, a rayon ribbon (now unfortunately discontinued) and it feels wonderful against the skin. It's so drapey that the shoulders needed reinforcement with grosgrain ribbon, but would be perfect for a drop-stitch scarf. (You may still find it on eBay.)
I can't see the link on your post so I don't know what gauge you need, but here are several suggestions for ribbon yarns that would work for your scarf. You can find them on the internet. (BTW, I just checked Hobby Lobby's Web site and was underwhelmed. You'll probably do better on the Net.)
. Charmeuse is a nice rayon ribbon by Judi & Co.
. K1C2 makes Tartelette, which blends nylon with cotton and has a nice texture.
. Gisha by Noro comes in beautiful colors; it's a microfiber/cotton blend.
. If you want something absolutely gorgeous, try Artyarns' Silk Ribbon.
The colors are fabulous and the feeling is beyond luxurious. It's about $16.50 a skein, but there's a lot of "air" in drop-stitch, so you can probably get a scarf out of one, or at most two skeins.
