Just about every time I post a picture of one of my tags, I get emails asking where I got them from. I'm really pleased people like them - thanks for letting me know.
Here's how I found mine: I googled "woven cotton tags", checked out the websites in Australia that did custom cotton woven tags/labels and then contacted each of them for samples. Once the samples arrived, I selected the one that suited me the most and went on to enquire about custom labels - sizes, what artwork they need, what colours they could do. Rather than actually tell you who I chose in the end, I think it's worthwhile running through that process yourself as we all have different needs, and there might be better/different manufacturers around since I did mine last year. This is the process I use to source lots of different supplies and services for my business, and I think it's a worthwhile investment of time - you never know what you might find out there!
