Aren't you tired that the in-game mannequins have only 6 poses available for them to choose from? They're all quite bland as well... This mod adds a new 'Custom Poses' interaction to the in-game mannequins, allowing you to choose from 54 new custom poses.

This new "Paint from Catalog" pie menu option lets sims choose and craft any In-Game paintings on the easel, that are available at their present Painting skill level... so no more scraping and re-starting, you're in full charge of what your sim will paint!
