Something you might find interesting and/or useful...
Legend Sisters offers trinkets and this/that but they also offer goth sewing patterns, notions, and fabrics! This is an interesting site that you might want to visit in your dark DIY questing. I haven’t yet ordered from them but I am eyeing that glow in the dark bat and moon fabric. Also A&L completely aligns with the philosophy on their about page as of this writing. Just wanted to let you all know it exists if you didn’t already.
Found this site thanks to Gothic Charm School.
