I scanned this from a Time Life book simply called Foliage House Plants. Confession: I kinda bought this book just so I could scan Mrs. Ubogy and her terrarium, which she clearly loves and dotes on. There’s a tutorial on how to make the terrarium in the photo, but good luck finding a bottle this huge and awesome. Oh also, you will never keep it looking so pristine. Mrs. Ubogy has you beat.
I also just wanted to point out that your mom was making terrariums before you were. But mainly, I love this photo.
The book is actually pretty good too, by the way.
