Running a bit late with my op shop show and tell...
I popped into Vinnies after school drop off, as you do and spotted this piece.
My brain started ticking. I was thinking terrarium among other things.
Actually, I spotted the top and when I went to pay my $1.00 the gentlemen mentioned the bottom 'was round here somewhere'. He fished about and presented me with the base. I happily paid my $2.00!
Oh the possibilities are endless!
