After a quick search on pinterest, there are a lot of people on etsy selling woven labels
https://www.etsy.com/shop/worldsalelabel is just one of them.
If you only want a small amount of them, I would recommend buying ribbon and buying iron on transfers, you should still get around 15 per page you print out (dependent on how large you want your labels) and you won't have to buy in bulk.
Let me know if you have any questions.
