Deb: Youe hefting tha bag of sakrete sounds familier.
I love to make things and learn new methods.
I made hypertufas a few years ago and hope there have been some improvments in formulas that withstand winter freezes.
Mine dissolved after 2 years and they were covered with plastic.
Marilyn: The tufa planter is just great. I believe the tufa mix is pressed into a form, as the mix gets to a certain height they add the glass ,then continue with tufa. Are the walls as thick as they look?
Man -oh-man.I wish i could make stuff.No controle and I need a prop to stand up.
On the other website there was a gardener who worked in "Papercrete" its similar to hypertufa.She could build large pieces using chicken wire armature
