I collected this sea glass with my mom and mom-in-law back when my wife was in the hospital. We had gone out to breakfast near the beach (to a favorite place of my wife, where we went when she got out) and for whatever reason, there was tons of sea glass. I collected a handful, but I haven't seen any since then.
The pieces were arranged by yours truly, after dumping them on this black foam board. I wasn't really going for a particular shape, but I think it looks like an anatomical heart.
[last year] this plant almost died, but we brought it back...
