I've seen these beads in a number of shapes and colors, but the tear drop suits the "sand art" bead very well. It reminds me of sand art in a bottle. This bead has a light summery feel to it, but I bet it would make a cute, light and airy wintery piece too. If it were mixed with some darker green tones and some orangy brown or red beads it would take on a different feel.
I like to force myself to take an opposite approach at times when beading just to see if I can!
Have a great evening!
