I made some updates to the files here:

New Images - The files are now borderless, allowing you to cut right on the domino edge. This reduces ink needed and also fits more cards on the page. Economic all around!

New Format - I also added a true domino sized file where the tiles are 1" x 2". I also updated the card file to the actual intended size of 1.5" x 3". Not sure how it wasn't that to begin with. Or it was and I goofed it up somewhere along the line. Either way, that's what they are now.

Thanks!
