Over the last few years I've produced dozens of apron card designs, and have sold hundreds of them to dozens of Pinsiders. I typically design or print an existing card set (often modified) when someone who has seen or purchased my work previously requests it (I also make tons of decal, 3D printed, and other mods for games).
Up to this point, when someone asks for an apron card set I design it then post it in the appropriate owners thread. However, this has recently become kind of an issue since stuff is scattered everywhere which makes it difficult to know for sure what someone is wanting with the PM me but don't reference the link to my post.
My solution was to create a website that features all of my card designs, some modified ones, and some originals from others who have given me permission to post them. The intent of this site is not to be a repository for others, nor is it a free site to download apron cards. Rather, it is a site to compile the cards I have created and/or printed, and am offering to sell.
All of my card sets are $10 per pair ($5 for an add-on card), and are made-to-order using the highest quality materials (price includes US postage). As stated on the site, I print the cards on a photo quality printer using OEM ultra gloss photo paper and OEM inks. I coat with a clear gloss vinyl overlay, cut to size, and color the edges in order to hide the white perimeter of the paper when installed. Regarding my digital files, I do not and will not share them, free or for a price, so please do not ask (if you do, the answer will be no).
Thank you to the dozens of owners who have purchased cards from me up to this point, and I look forward to helping many more add a little style to their pinball aprons.
You can find all of the cards I currently offer at http://aproncards.com
FYI, as of 6/27/20 all apron cards are on hold right now. The issue is that I'm out of clear gloss vinyl, and the product I use is on back order. I bought and tried another brand with the same specifications, but it just wasn't up to the quality standard I wanted. If you are interested, go ahead an PM me so that I know to contact you when I'm resupplied.
