Hey Pat,
Those look nice!
I made some using cement and rock salt. The salt was supposed to make it lighter but they still weigh a freakin ton. Also the ones I formed didn't look so hot but when I gave up... the cement and salt I left in the bucket looks great! Go figure.
Did you do 1:1 cement and crushed coral? What did you use to form them?
I want to give it another try and yours look great! I'll try doing it your way.
Thanks!
Jenny
