You can turn leftover jam jars into charming, useful projects that fit any skill level or occasion. I’ll show you simple ideas that save jars from the trash and turn them into gifts, home décor, storage, and mini planters you’ll actually use.

Let’s jump into a bunch of fun options—tiny shakers, tealight holders, herb planters, gift jars, and more. Pick whatever fits your time and style. I’ll keep the steps clear, the supplies simple, and the ideas useful for holidays, organization, or quick handmade gifts.
1. Mini jam jar salt and pepper shakers

I grab empty mini jam jars and poke a few tiny holes in the lids—instant salt and pepper shakers.
They look sweet on the table and make a reusable gift.
I just label each jar so everyone knows what’s inside.
2. Jam jar tealight candle holders

Old jam jars make easy tealight holders—I wrap them in twine, glue on beads, or frost the glass for a new look.
They’re quick, and as long as you use heatproof jars, they’re safe for tealights.
3. Mini jam jar herb planters

I fill mini jam jars with pebbles, potting mix, and little herb seedlings like basil or parsley.
A label on each jar and a spot on the windowsill, and I’ve got fresh herbs for cooking or gifting.
4. Hot chocolate mix gift jars

I layer cocoa, sugar, and marshmallows in jam jars for a cozy gift.
Tie on a ribbon, add a tag with instructions, and you’re set.
Sometimes I’ll switch it up with peppermint or caramel for something different.
5. Valentine’s Day mini jam jar favors

I fill mini jam jars with candies, little notes, or homemade jam for simple Valentine’s favors.
Decorating the lids with twine, washi tape, or tags makes them feel special.
I usually pile them on a tray so guests can grab one—quick, cute, and personal.
6. Jam jar fairy light lanterns

I turn jam jars into fairy light lanterns with battery string lights and a bit of tissue paper.
They work as gentle night lights or table centerpieces for parties or just cozy corners.
I either seal the lid or punch a hole for the wire so everything stays neat inside.
7. Mason jar snow globe crafts

I glue a tiny figurine to the lid, fill the jar with distilled water and a bit of glycerin, and add glitter for that slow snowfall look.
A tight lid and a decorated base finish it off. These make fun gifts or shelf decorations.
8. Mini jam jar spice storage

I use empty mini jam jars for spice storage to save space and cut down on waste.
Lids get labeled with a marker or stickers so I can spot what I need quickly.
Grouping them on a tray or a magnetic strip keeps the kitchen organized.
9. Jam jar succulent terrariums

I like turning jam jars into tiny succulent homes, layering pebbles, charcoal, and cactus soil for good drainage.
Open jars keep succulents dry. They do best in bright, indirect light and only need a bit of water.
10. Mini jam jar bath salt containers

I fill mini jam jars with homemade bath salts for easy gifts or quick treats.
Layering colored salts or adding dried flowers makes them look extra nice.
Labels and tight lids help keep the scent fresh.
11. Jam jar layered dessert cups

I layer cake crumbs, whipped cream, and jam in small jars for single-serve desserts.
They travel well and look neat at parties.
Sometimes I’ll toss in fruit, chocolate, or nuts—whatever sounds good that day.
12. Mini jam jar seed starters

I use mini jam jars to start seeds since they hold soil and moisture well.
A layer of pebbles for drainage, then potting mix, and I gently plant the seeds.
Labels help me keep track, and I set them in the sun, watering just enough.
13. Jam jar button and embellishment storage

I sort buttons, beads, and ribbons into jam jars. Clear glass lets me see everything at a glance.
Labeled lids make it easy to grab what I need. Stacking jars saves space on my craft shelf.
14. Mini jam jar jewelry holders

I turn mini jam jars into jewelry holders with just a few tweaks.
A cork or padded lid and a glued-on ring holder or dish on top, and I’ve got a spot for rings, studs, and chains on my dresser or nightstand.
15. Jam jar homemade jam gift sets

I like to pack small jars of my favorite jams with a loaf of bread or a handful of tea bags for a simple gift.
Usually, I scribble out handwritten labels and top them with cute fabric lids—makes them feel a little more personal, doesn’t it?
I wrap the sets in kraft paper or tuck them in a basket, so they’re all set to hand off.
