Wares are crafted in the crafting screen by using resources found in mini-game. Players earn a crafting session by playing 10 mini-games. Those resources are converted into wares by crafting them.
Once the wares are made, they can be sold in your shop by dragging the icon from the left inventory panel and dropping them in the appropriate shelves. Their placement can be tweaked once placed.
Customers prefer two specific types of wares categories. They also prefer two items from other categories.
