If you have a membership, there are a few in Designs. Go to Design, click 'mouse' in the tags and you'll find a number of them, but not a real set.

Check out Embroidery Library, though not a set and designs by Sick, he has a set

Good luck, Ava! Maybe by bringing this to the top you'll get more suggestions. Personally, I'd poke thru the designers at Oregon Patch Works, lost of super digitizers there, see what they may have, and they're having sales right now, all different % off, but all good. Hugs, Marji

You have some good answers. Hope u find what u are lookigfor *
