I wonder if (not actually a spoiler, but speculation sometimes gets flagged these days)
they make a contract for exclusive use of the floral technique, but since it's so easy and someone else independently recreates it, they could hold the family liable for breaking the contract?
Also, love the pencil cap, and how just all around capable at arts and crafts Lily is.
Kyle??? The pencil and all that. And Madam Barnes was just saying how Aristocrats can't do labor (idk if painting is considered labor in this setting).
Rather than have them be so focused on being married- they'd make good crafts women; that part about no labor for aristocrats is too bad tho- they could be free of patriarchal pressure to a degree if not for that... they can still start a business and commission artists and craftsmen after teaching the technique (and patenting it) tho I suppose.
