Baby food jar crafts

[JHKLHZHARH]

I have approximately 50 baby jars and lids. My 6 year old DD wants to make something with them for Christmas.

Do any of you have any ideas you could share.

TIA

Could you make candles with her? Buy some cheap wicks and melt the wax?

Paint with glass paint or nail varnish: colourful tea light holders.

Mini terrariums. Bit of moss on top of some soil and sand. Add teeny fairy ornament or something to that effect.

Mini snow globes - Christmassy! Could use glitter.

Wish/memory jars. Fold teeny bits of paper with happy memories or positive pick-me-up quotes written on and fill the jar then decorate the outside or make a pretty label for it. Could be a cute gift for her friends?

Snow globes. Stick plastic cake decorations to the lid. Fill with water and glitter. Glue lid to glass. Hurrah!
