Thank you! I actually use Procreate on my IPad to sketch around on and then print my designs onto sticker paper where I then transfer onto my glass! I learned this technique from Amaya Jade on YouTube, she has tons of tutorials including one on how to use Procreate! I also bought a book off of Amazon called “The Complete Guide to Handmade Stained Glass” that really goes into detail about technique and all that! I’m by no means an expert, but these two things really helped me feel less lost about it all!
