Maybe someone else can give you picture posting instructions, though that information is somewhere on this forum. I have my photos that I post on Photobucket.
You can use aluminum flashing, large plastic trash cans, large plastic pails with the bottoms cut out and duct taped together to make molds for pillars. There are many things you can use for molds. Just make sure you use the right "release" e.g. plastic bag, motor oil, vegetable cooking spray. When using a bottomless mold make sure you have adequate weight on the top or the mold is tied tight to the ground or the mold will float up as you add cement mix. You can use PVC tubing or smaller plastic buckets taped together if you want the inside of your pillar to be hollow. Have you asked at local carpet dealers if they have cardboard tubes for their rugs. Pretty soon everything you look at will become a mold. Good luck! Billie

Thanks for taking the time to reply Billie. I have made a mould and was looking for something to strengthen papier mache.?

I'm a little confused. Are you saying you've made a mold out of paper mache and you want to strengthen the paper mache mold? Or your working with paper crete and not hypertufa? Details please, for the reading impaired. lol! Billie

I am using paper mache to make the mould shape then going to cover it in liquid latex..I don't know if this work...hopefully it will make a latex mould that I can fill with hypertufa mix

There are a bunch of ways to make to column molds. I bought mine ( http://flexteck.stores.yahoo.net/tucomo.html) but if you a search for concrete column molds you find a bunch of ideas. Some of which with a little thought you might be able to build out of cheap materials.
Also Lowes is now selling a bunch of History Stone Molds

Here is a link that might be useful: History Stones Column Mold

Thanks so much for the ideas and info guys and gals. I have now made a mould in latex then supported the latex by spraying expanding foam..otherwise the latex would deform the shape due to the weight. when done the pillars are going to be somewhere shady. What would you suggest be the best recipe for the tufa..I have seen all kinds of ratios. I was considering 1 part portland cement, one part Peat moss and one part perlite....

Update:

I managed to make the large pillars the smaller pillars the snakes and the skulls as you can see..and a few bits and bobs.

I know want to make some pillars using polystyrene fish boxes the kind they use for transporting wildlife I think they are also used for dry ice. However reading the articles on the forum saying that hypertufa will not adhere to polystyrene. Has someone had any experience of doing something similar with Polystyrene? would I need a contact adhesive? any help would be gratefully appreciated
