Worth a shot! Wonderful work everyone.
I think the only specific thing to make sure is that it has a usb c port. (If you are getting the newest ones)
I know some people have had issues getting the 4k to display on the new cintiqs if you don't have a usb c port. (they have an adaptor but its not reliable)
Also desktops (pc or mac) give your more powerful specs for the price compared to laptops, if you want a mac buy a refurbished one from apple, save a bit of $$!
my two cents
Thank you for sharing, your detailed step by step has me thinking about how I could do something similar.
I have a suggestion for you as well, you might want to consider selling on gumroad.com as well. It’s really popular for digital artists content (like tutorials etc.) and the fees are super low . I’m not sure what the fees are on Etsy these days but I remember them being pretty high for physical products.
Is the digital only clip art market big?
