By now everyone has a set of glass blocks, but several years ago they were an "ah ha" moment for us. We saw they in South Carolina over Thanksgiving and came home and made many blocks for friends and family as gifts that year.
We used all white lights, but I may make some more with multi-colored lights next year. I love the soft glow they give to the floor.
What could be nicer than watching the seasons come and go in the garden. I hope to retire in about three years and spend more time just digging in the dirt. I'm not a professional gardener, but enjoy putting my hands in the dirt and seeing what happens.
For now, let's enjoy it together!
