Are there BOUNDARIES that keep them separated from each other ? And what causes them to eventually merge, forming bigger and heavier drops (that is, if they do eventually merge or they remain as separate drops !)
This phenomenon is called "Surface Tension" or by another definition "Hydrostatic Surface Tension." Google Search provides abundant scientific information about this subject ... probably more information than I could ever read and / or understand !
A Google Image search for "water drops" provided extraordinarily beautiful sources of inspiration ! [Thank You Google !]
I used hand-dyed silk for the background of this quilt, then mounted the quilt on 2 layers of batting to provide extra depth. To separate the "rows" for the droplets, I used Madeira and Sulky metallic threads to create vertical columns in random widths.
And then the fun began ! Using "Swarovski" Crystals, and other purchased "Hot Fix" notions, I used my Hot Fix heat tool to apply each of the 'water droplets' onto the background .... one little, tiny piece at a time ! Seen in just the right kind of light, the crystals, et al glimmer and shine just like tiny water droplets.
