So, you do know what a terrarium is, don’t you? I’m assuming you do. If you’re anything like me, you’ve asked yourself before ‘What is the purpose of a terrarium?’ Well, there isn’t one specific answer for that, but we’ve noticed a big spike in their popularity in modern decor. They’re everywhere! It came as a surprise to me too, but they’re they always look beautiful. Whether it’s a do-it-yourself project or bought pre-built, when placed on a side or console table among other simple decorative accessories, it’s sure to look great.
