I've seen a few FrankenSets out there - for example John has a Braves set and a Uniform Number Set, Tom has a Cubs set, Nick has the Dime Box FrankenSet, Robert has a serial numbered card set, Night Owl has a night card set. Jeff's got a White Sox FrankenSet. I'm sure there are many others. Tell me about yours in the comments!
I decided this would be a good way to at least start organizing my Twins cards.
My own "rules" for the set are pretty simple -
1. Each card should be a Twins player in a Twins uniform (and exclude multi-team cards)
2. If at all possible, each page should have 9 unique players and 9 unique sets
3. Have Fun (Mandatory)
