This is a fairly simple question, however, my experience with Google makes it seem much more difficult. What is a good website for getting non-bulk kippot in personal styles (eg. velvet, suede, knit/crocheted, not these cheap, satiny types one might find at many heterodox schuls)?
Try http://www.judaica.com/. I ordered a few items from there (not kippot), previously. I was quite pleased. I just browsed the kippot area, and they have a wide selection of styles and a wide price range. Pricing seems pretty reasonable to me. (Then again, lately, I'v been getting most of my kippot for free from a Bar Mitzvah or wedding, somewhere.)
Keter Judaica has quite a nice selection of yarmulkes, available in many materials, both traditional and modern, and in bulk if needed.
You can try Eichler's collection of yarmulkles. They seem to have what you're looking for. That page has links for lists of Kippot and Yarmulkes that are velvet, suede, knit, or "customized" (as well as for events), to be sold individually (ie not in bulk):
Here, you can find kippot in knit, suede, satin, and velvet as well as hand-painted children's styles, kippot for babies, and much more. [...] Finally, for those who need their kippot in bulk, we have you covered with our Kippot by the Dozen!
