One option are label fabrics, for example this one here:
https://www.missouriquiltco.com/shop...-cream-yardage
Another possibility would be spoonflower.com. There you can design your own fabric, so you could just make a yard of labels with a gap for title and date that you can fill in later.
Or you could get personalised labels from someone on etsy.com. Here are some options:
