There are a number of small facet sets that are also very suitable for installation in tea lights and candle holders. This flower is certainly one of them.
Just take four sets of facets and choose a matching background glass to go with them. Here in the example, I chose the Uroboros 11-38. This glass is one of my favorite confetti glasses. The bright colors express such a positive mood.
Of course, you can also cut the motif from other glass.
