I’m a trisStalker , TrisWorshiper & CisYeredere! (Physically harmless)
so here’s some shrine tips and ideas (when I remake my shrine it'll include theses!)
photos (school pics, group, etc etc.).. this is a bit obvious but your supposed to worship your darling, many gods had their image created and shown so you can worship them!
dried favorite flowers, favorite candy wraps, etc etc! Show their favorites, show that only YOU know them well enough!
wooden / clear figures / etc. at least I’m personally planning to buy a few figures that I think show me and my daring! (++ points if you paint them to look exactly like you & your darling!)
poetry, book pages, etc! Anything that’s sooo you and your darling!! Even if it’s romantic pages or obsession!
prayer like or worship things (I can’t think of words :p). Set up candles, alter, etc!
trinkets of their hobbies/interests! Keychains, figures, etc.
hair, clothes scraps, etc. whatever directly theirs you can get!
a notebook to write down their favorite things. Remember you should know their favorite things, all of them
keepsake box. Keep their hair, teeth, clothes, etc in it. Or items you find of theirs!
stuff you make as gifts, it is great to have a backlog and gifts!
if you can sew (or buy a plush), you should make/buy a plush of their favorite animals & sew/buy cute little clothing to look like your darling! Or even better, both of you! So you two can be little cuties together!
their Religion stuff, this is a bit more ehh tbh, but personally I plan to keep other religious imagery in my shrine cuz my darling is religious, and I’ll follow it too cuz he’s my darling and my world!
PHOTOS PHOTOS PHOTOS. Any of them, even if it’s a bit, weird how you got them! If your friends get the pics, well what amazing friends! And great for you too :D
if you have clothing like theirs, or like their favorite clothing, then I’d say sacrifice that clothing so you can have a replica of your darlings clothes! Especially you just can’t ruin their clothing.
sketches, writing, etc. if you dedicate your love in art, then you should display them next to your darling!
