"With wizards doing it, Carissa thought it wasn't effective to have multiple wizards working on the same item, so a single wizard works on all stages of the item, but they trade off stage-assisting items among each other as they individually reach particular stages of their work on the headband."
"Does your method allow nonwizards to specialize in a single aspect of a headband and move from headband to headband in the process of assembly, so that they can master that single stage of item crafting? How does speed compare to nonwizards, are there Intelligence requirements, are there math requirements, does the person have to go through a stage of learning to sense magic the same as if they were learning to construct a spell scaffold?"
