This lora attempts to create a consistent wooden tankard of the "medieval/Fantasy/Ren-Faire" type.
I revisited the data set I used for the Illustious version, and tweaked it a bit for SDXL
Training words include " tankard, wooden tankard, holding wooden tankard".
Images generally come from real photos (of ren-fair/re-enactors) with some digital art thrown in as well for variety. Most of the background settings were "tavern" so that is pretty strong (especially if you use it in the prompt) but I fiddle-faddled with it and it seemed to work ok outside of a tavern (just put tavern in your negative)
Good luck, and....
Cheers!
