I have stitch marker jewelry listed now (my own invention, thankyewverymuch), but I also make soap and lotion bars.
I can offer a discount on custom orders. I usually charge $25 for custom necklaces, but for you guys, I'll do it for $20. I also make "empty" necklaces and bracelets for $10 so you can wear 6 of your own favorite markers. You can also make 6 markers for your pal and get "empty" jewelry to put them on.
