I recently created an Instructable and video tutorial on making a low maintenance succulent terrarium and thought gardeners world readers might be interested. The project basically involves modifying a glass jar, creating a suitable environment, planting the plants and installing the night light.
I made these as Christmas presents for my family (hence the low maintenance part ) and think they would make a nice gift or decorative piece for a windowsill.

I'd love to hear what people think and any suggestions on improving the project for future versions.
