Hey David! Depends on the design for me. Let’s say I’d made a travel print for Bryon Bay, in Etsy my SKU would be “Bryon” and Printshrimp would match in order for sales to integrate. If I make a variation of the Bryon Bay print, my next SKU in Etsy would be “Bryon_1” and again, Printshrimp would match. On my computer the saved file would be “A0 bryon_1 MASTER” I also have a HUGE Canva document with all of my designs in them, I just also have the files saved on my laptop for mockup purposes and on the off chance I lose access to my Canva files one day. As Mihai said above, has to make sense to you! What might work for a shop with 100 listings might not be feasible for a shop with 1000 listings 🤷♀️ Hope this helps!
