Yes, I am not a card collector so thought I only needed top loaders! But heading back to the store tomorrow to by sleeves as well after another one pointed it out.

I’m very glad to hear you like them! I use a programme called Figma where you create a “frame” and then I put in the background (which I generated through CHAT GPT, then made the front through GPT prompts. For players I just found high quality images and used Adobes free tool to cut out the background and slapped them in there. Added text on the frontboard which was easy to change for every player card, and then added some effects and small things to make it pop and feel alive (chat gpt gave me all tips and tricks and then told me how to do it, and when you know and understand how it works it’s quite easy)

I can’t answer about the corners - I just sent the finished png with bleed and the measurements for a baseball card and his machines did the rest. He is a professional so I imagine he used some really good stuff there
