One Large Glass Icicle Suncatcher I’m so excited about these icicles. As the weather is getting colder, they’re a joy to hang in my window. I make them with borosilicate glass and each one is individual. No two could possibly be alike. These large icicles range in size from 5” to 7” long. I also have small ornament icicles available in another listing. Those range from 3.25” to 4” long.
