My El/Jane Hopper Headcanons (because those evil misogynist brothers refused to let her be a person):
In Lenora, she taught herself how to knit, and so every member of the Byers family has the wonkiest scarf known to man
Later, when she’s a much better knitter she tries to take them back but when everyone refuses she ends up sneaking into their rooms to fix them, Will wakes up to this once and thinks Vecna is back from the dead and knitting in his room
She likes crafting in general, Joyce taught her how to sew, and she scrapbooks everything
She gets into DnD for the figurine painting
She likes learning but never goes back to school (Owens acquires her a diploma)
As a young adult she doesn’t really know what she wants to do with her life and basically does every job a person can do
She had a brief stint as the receptionist at the police station but was fired for showing favouritism (it was towards Callahan not hopper)
Her music taste is very eclectic, she loves music that has really intense emotions and gets really into riot grrrl in the 90s
She loves fashion but especially loves flowy hippy 70s stuff
She loves a funky accessory, especially earrings and headbands
She helps Jonathan with his films when’s he’s home, especially with making costumes
She starts volunteering for costume making with the Hawkins theatre troupe and makes the party volunteer with her when they’re back in Hawkins (Dustin needs no convincing he loves this shit)
