  4. Spice storage – I bet you’ve seen tons of organized pantries with spices in jars. It is a cool way to repurpose smaller glass jars.

  15. DIY glass jar lamps – Glass jar lamps can be a fun DIY project. WikiHow has a great guide on making glass jar lamps.

  17. Sand and seashell souvenir gift – An easy and cute souvenir that you can use for decoration or as a gift. Collect a bit of sand or rocks and a bunch of small seashells. You can add anything that you have to make it more unique.
  18. Cookie dough mixes /or bath salt mixes/ – Take a clean & Dry jar and start layering the dry ingredients. It is a fun and easy-to-make gift idea. If you want to make it for someone, you can add a note with instructions. You can follow my recipe for DIY chocolate chip cookies here.
  19. Advent calendar – A quick and easy craft idea that can be ideal for holiday celebrations like Christmas. Place a number on each of them and get creative with the decoration. You can put a small treat in each of them, like homemade cookies, a note, or a riddle. It will be more thoughtful and less wasteful than the ones they sell in the supermarkets.
  20. Herb garden – Add small rocks & pebbles, so the water can drain under the soil, and the roots won’t rot. Then, fill the jars about halfway with soil and add the herbs. 
  21. Terrariums – They are easy to make, require low maintenance & are cute. To do it, fill the bottom of the jar with small pebbles & add charcoal after to reduce bacteria, fungi, and odors. Then, addd the soil and the plants. Decorate with pebbles, moss, and other natural decorations.
  22. Candle holder – You can place some candles or Christmas lights and make a cozy atmosphere.
  23. Leftovers – Jars are ideal for leftovers, even if you are eating outside. It can come in handy and help reduce food waste.
  24. Growing sprouts – Sprouts are healthy & flavorful additions to your meals. To make it, add 1-2 tablespoons of the sprouting seeds in a jar. Cover with 2 inches of warm water & let it sit overnight. The next day, use the cheesecloth to drain the water. Add water to the jar to rinse the seeds, and drain again. Repeat this twice a day, every day, until your sprouts get a bigger size. It will take between 3 to 7 days, depending on the type of sprout you’re growing. 
  25. Coffee ‘cup’ to-go – Instead of using single-use paper cups, you can bring a jar and use it as a ‘cup’ on the go.
  26. Root house plants to make new ones – Cut a root node from a plant you have and then place it in a mason jar filled with clean water. Change the water every couple of days and watch the tiny roots grow. Place the jar close to the window with bright indirect sunlight.

  1. I REUSE glass jars and forgo buying them. Spaghetti sauce, mayo, jams etc that came in glass containers were collected. New lids can be purchased on the Web, if needed. Ball lids fit the mayo jars. Great ideas for jar use…thank you!
