This is cute! I have a handful of sea glass but not big enough. I want to know where did/how did u get yours? I heard u can fill a jar with sand and glass and shake it up. I don't know if that works.. :-)
All my glass is natural, I walk the beach almost every day when low tide isnt during work. Ive heard that if you fill a bottle with glass and sand and water and tie it to a buoy the sea will churn it.. but ive never tried.
