How about this:
Getting Crafty! (EP)
Idea: I thought it would be extremely neat to have optional crafting available in the sims to be expanded upon more. What if we have an expansion pack that is exclusively dedicated to different types of crafts and the ability to use those crafts as a means to earn simoleans? There are plenty of varying crafts in the world, so why not incorporate these into the game. Heck, I do some crafting partially as a hobby and for business. Here are some ideas below.
Aromatherapy Craft (The herbalism skill can be put to good use here as well), sims can create an array of finely scented products from soaps, to candles, and even specialty oils. Sims can earn the holistic trait or earn an uplifted emotion from creating a successful blend/product.
Glass Blowing Craft, sims can create beautiful pieces of artwork from glass!
Pottery, Sims can make their own vases, trays, and what not that is not available in buy/build mode and can sell it for a nice buck if it's nicely made.
Woodwork
And maybe our sims can start their own website and earn money from selling their wares online or maybe selling their items in shops?
