Finally, here it is: how to make your own labels tutorial.
It's a very easy thing to do, but it requires some time. Of course there is an easier and cleaner way to do your labels using Spoonflower (I found a tutorials on this some time ago. I will link it later) but I'm always afraid that I will pay much more on the shipping fare than the product it self.
So here it goes, my way on making labels.
Materials needed: the stamp of your brand, fabric paint and an ink pad. I've had my stamp done professionally and because it has different from normal dimensions I couldn't find an empty ink pad to fit it, so I asked my father-in-law to make me a custom ink pad. As for the fabric paint I used the left over of the black paint I used for making the moustaches on my moustache dress.
