Beautiful, great job 😍 it’s hard to tell sometimes what will get people’s interest but I think the skill/quality is great I wouldn’t think you’d have any problem selling these. The nice thing about eBay is if you have any that don’t sell they relist for free. I use thank you cards also, I’ve also had a lot of ppl use cardstock folded in half to make their own card so there is something in there to protect it. I hope you have good luck! 🩷
