I’m a sucker for a good thrift-store rescue, and this little autumn terrarium display is exactly the kind of project that makes me hang onto “junk” a little longer than I probably should. If you’ve got three old glass fish bowls collecting dust in a basement, garage, or cabinet, this is such a pretty way to turn them into seasonal decor that looks thoughtful instead of thrown together.
What I love most is that this project is simple, fast, and very forgiving, which is ideal if you want your house to feel festive but you’re also balancing work, dinner, and a hundred other things. I’ve made versions of these for a dining table, an entryway console, and even a kitchen counter, and they always add that cozy fall look without needing any special crafting skills.
Materials
3 old glass fish bowls, small/medium/large sizes, about 6-inch, 8-inch, and 10-inch diameter
Instructions
1. Wash the fish bowls with warm soapy water, rinse well, and dry them completely so the glass stays clear and the filler materials don’t trap moisture.
2. Arrange the bowls in the order you plan to display them, usually smallest to largest, and decide which side of each bowl will face forward.
3. Add a 1-inch layer of pebbles to the bottom of each bowl to give the display weight and create a clean base.
4. Tuck moss over the pebbles in each bowl, using enough to soften the base while still letting a little of the stone show through around the edges.
5. Coil the fairy lights loosely into the medium and large bowls, leaving the battery pack hidden at the back or underneath the moss near the opening for easy access.
6. Place the mini pumpkins or gourds into the bowls first, using one larger focal piece in each bowl and smaller ones around it for balance.
7. Tuck in pinecones and acorns around the pumpkins, angling them naturally so the arrangement looks gathered rather than packed.
8. Slide faux autumn leaves into open spaces near the glass so their color shows from the outside, and secure any stubborn pieces with a tiny glue dot or a bit of removable putty.
9. Wrap a strip of burlap ribbon around the outside rim or widest point of each bowl, trim to fit, and secure the overlap with a small dot of hot glue.
10. Tie a simple jute twine bow over each ribbon seam to give the bowls a finished, cozy look without covering the glass.
11. Turn on the fairy lights, fluff the moss and leaves one last time, and group the three bowls together with a little space between them so each one stands out.
Variations & Tips
For a more neutral look: Use cream pumpkins, brown pinecones, and muted leaves in tan and rust tones. I love this version if your everyday decor is more calm and minimal.
For a dining table centerpiece: Keep the middle bowl tallest or fullest, then place the two smaller bowls on either side. It feels polished but still low enough that people can talk across the table.
Use what you already have: If you don’t have acorns or faux pumpkins, dried orange slices, cinnamon sticks, or extra pinecones work beautifully. This is one of those projects where a little improvising usually makes it feel more personal.
Keep the battery pack accessible: Don’t bury it too deeply under moss. I learned that one the annoying way when I had to half-empty a bowl just to switch the lights back on before dinner guests came over.
Try a porch-safe version: If the display will sit in a covered outdoor spot, use only faux fillers and skip anything that could mold or break down with damp air.
Make cleanup easy: Build each bowl in loose layers instead of gluing everything in place. When the season ends, you can separate the materials quickly and reuse the fish bowls for winter or holiday decor.
