Why have mason jars become all the rage these days? Well, they have so many uses that people are enjoying repurposing them around the home and office. First, you can certainly use a small mason jar for that morning oatmeal of yours. What’s even better is to make the oatmeal at night and then have overnight oats ready for you when you get up in the morning. But mason jars aren’t just for food. You can use them as vases, putting a few pretty flowers in each one and enjoying them. You can also decorate them with stickers or using permanent markers and use them as coffee cups. You can also put soil in a mason jar and use them as planters for a beautiful and eclectic garden.
