I've seen QR codes before, but have no clue how to create one. I'll look into link tree and see if I can get that set up. The card has a spot for a QR code. So, that's good.card looks good but they're going to have to search for your threads.
I would look at setting up something like Link tree and include a QR code. The QR code would take them to link tree and you link tree page would have a direct link to each thread, your youtube channel and anything else you want to add later. They dont even have to take cards. Hell you could put a plaque/poster on the car with the QR code even
Thank you DSG!!!
