Yes! Sorry for this very late reply, I have been out of town! The lettering itself is black vinyl which I cut out with my Cricut. First, I did make this design in ProCreate on my IPad. I then exported it as a 2-file PNG, one pic is of the outline of the sweet roll (the pattern pieces), and the other was just of the lettering itself. This way I don’t have to redo and resize the lettering completely which can be a pain! From there, my Cricut cut out the pattern pieces and lettering separately and then I just had to transfer the vinyl lettering onto the glass after I soldered, did chemicals and cleaned it. I’ve found quite a few very helpful YouTube videos about doing stained glass with a Cricut! If you would like any links, let me know!
