10 Creative Ways to Reuse Flat Mason Jar Lids

05.06.2021 | Kim Norcross | THIS BLOG IS ABOUT JAR LIDS

Save money by reusing flat lids and putting them to work in another way!

If you've attempted to use a flat lid for a second round of canning, you've probably ended up sorely disappointed at the spoilt food that resulted.

Although flat mason jar lids can only be used once for canning shelf-stable foods, that doesn’t mean you need to toss them after a single use.



At, we want to help you find creative ways to reuse what you already have, so you can save money and reduce waste.

We use and reuse mason jars for EVERYTHING, and reusing flat lids is no exception!


But FIRST, how do you know if a flat lid has been used for canning or not?

It's easy!

In the following image, you can see an unused flat lid on the left and a used (aka hot water bath sealed) flat lid on the right.

You can clearly see the indentation that the canning process has left on the seal of the flat lid.

Here is a list of 11 creative (and simple!) ways that you can keep reusing your flat lids, even after they've been through a round of canning:

(If you prefer to stash the rings and buy new flat lids for your next canning project, these first 5 ideas are for you!)

1) Christmas ornaments

Christmas may seem like it’s months away but, as the saying goes, “time flies” and the holidays will be here before we know it!

Stash flat lids and make DIY Christmas ornaments to decorate your tree or give away this holiday season.



2) Pumpkin craft

For the friend who love “pumpkin spice everything”, all you need is orange craft paint, glue, 3 flat lids and a piece of wood to create an adorable DIY pumpkin.


3) Mason jar lid magnets

Magnets are another fun personalized gift idea! Glue a photo to the metallic side of a flat lid, and a magnet to the back for a unique magnet.

Make a magnet with a photo of your child or their name and use it to attach their latest art project to your fridge!

You could use patterned paper or magazine clippings instead of photos, the possibilities are endless!

4) Chalkboard tags

Paint the metallic side of the flat lid with chalkboard paint, drill a hole into the lid and use twine to hang your easy to make, reusable chalkboard tag on anything! 


5) Mason jar lid coasters

These mason jar lid coasters would make a great gift idea and can be made with or without the ring.

6) Freezer foods

YES! You can use a flat lid that’s been sealed and used for canning for your freezer food projects!

Because the food is being frozen, the seal doesn’t need to be 100% air tight like it does for shelf stable canning.

7) Mason jar lid desserts

Can it get any cuter than a single serve strawberry pie with a lattice crust, in a mason jar lid?! We love that these sweet treats can be baked and served in the mason jar lid, making prep and clean up a snap!


8) Dry food storage

Reuse canning lids and mason jars to store baking essentials and spices in your kitchen.

9) DIY gifts

Mason jars are great for personalized DIY gifts, and you can seal them with a used flat lid and ring for a self-contained gift and wrapping!

Home made candles, bath salts, and hot chocolate mixes all fit perfectly into a mason jar. Or, fill a mason jar with chocolates for an extra yummy treat!

10) Bulk cleaner storage

 If you buy laundry soap or other cleaning products in bulk, use a mason jar with a used canning lid to hold a smaller portion for easy everyday use. If you use a local refillery to stock up on home cleaners, a mason jar is the perfect container to fill up and leave on the shelf.
