You can choose whether you want to gather all the resources manually or just abstract away that you have the materials you need on hand. This is to give players a little bit of freedom on how granular they want the game to be (for example if you're playing an alchemist you may want to be granular about potions but not about tailoring).
There is a mechanical change I want to highlight depending on your approach, if you abstract away having to get all the materials when you use the move Reap the Benefits then you'll only gain (1) value of your crafted item per filled box.
This means you ultimately get a little less for your efforts, but since you didn't have to get everything from scratch it all evens out. 🐮
