That was just the response I was hoping for!
My plan is to post completely unique t-shirts using my own hand-drawn imagery so I'm hoping they'll stand out.
I can't remember if I mentioned it but your course is awesome - it was just the introduction I needed to get me started on Merch. The information about what to avoid, what sells well and just the to-the-point information about image resolution and ppi was so useful!
Thank you @philemerson glad you liked the course. :)
