I LOVE jars. They just feel so rustic without meaning to. I managed to collect a fairly large number over the years, either as gifts from friends or ones I grabbed at a thrift store. I've created a list of creative ways to use those extra jars lying around.
Make a Terrarium or Plant Holder
This is perfect excuse to get another plant for the house. Check this Huffpost article out for how to make an empty jar a new home for your plants! This is also a good use for old peanut butter jars.
Storage
Clean and dry the jar, then place things in it! It can hold pencils, kitchen utensils, paintbrushes, you name it! You can even customize the jar with some paint and labels.
Food Storage
With the same idea in mind as above, safely store your dried herbs, flowers, spices, and other food products! I personally keep my dried botanicals in large mason jars before sorting them into bags for my shop.
Food Dish/Drink
Eating out a mason jar is a great way to feel good about eating a salad (especially if you need to motivation to eat healthy).
Candles
Follow these WikiHow instructions to make a lovely mason jar candle! I think it adds a personal touch when compared to regular candles.
Home Decor
Give your home a rustic look with a couple of mason jars, dried flowers, and an piece of wood. Dried yarrow, hydrangeas, and baby's breath are some of my favorites.
Wedding Decor
A perfect way to add a rustic look to your boho wedding. And it makes for cheap but stylish decor!
You can also put some stringed lights inside, to make a lovely DIY lamp. You can get battery-operated ones for cheap at Walmart.
