Pete's stainless steel soap moulds

Since I wanted to start making soap I thought I'd better get some moulds.  You can buy plenty of fancy moulds online, but I just wanted something simple and the right shape for our soap shaker.  I went to th op-shop and checked out various containers, I did find a little silicon mould which is good for the overflow, but the plastic lunchbox I bought didn't let the soap out and we had to cut it off.  Pete decided to make something, and this is what he came up with....

Its a piece of stainless steel plate folded up in a "U" shape, with steel plates help in place with booker rod and nuts.  I made gaskets from a truck inner tube to seal the ends.  When the soap is set, you just undo the bolts and the soap slides out of the mould.

Do you have any creative alternative soap moulds?

You can get all my tallow soap recipes in my eBook Make Your Own Natural Soap, more information here.

 Would you like to try making your own soap from natural ingredients, but don’t know where to start? 
This eBook will take you through everything you need to know to make simple soaps from natural ingredients, including herbs, clays, charcoal, oatmeal and coffee grounds.

It also explains how to use tallow in soap. Tallow is cheap and locally available, and it makes long-lasting moisturising soaps, it is an under-utilised ingredient in home soapmaking in my opinion. This eBook includes 10 recipes specifically designed for tallow soap.

  1. Any hints on where to get a soap shaker? I haven't been able to find one, other than a silly little thing someone is selling on TradeMe here in NZ that only holds a tiny round soap - which means chopping up bars of soap - made out of tea strainers! I want the old fashioned square sort that hold a bar of Sunlight Soap.

    Love the look of your moulds - maybe one day I'll get into soap making.

    1. I got mine from.
      Expensive, but very good quality and supports a small business.

  2. What a great idea. I've just made my first batch of soap 2 weeks ago. You can read about it on

    1. well done! I'm sure it will be a first of many.....

  3. Okay, so I found one on a website that has been 'out of stock' for about a year and a half! :)

  4. What awesome moulds :) Soapmaking is something I keep thinking about doing,and then set it aside for another day. I do love the look of everyone elses soaps though - I guess one day I will have to give it a go.

  5. Hi Liz, please tell Pete that they are awesome soap moulds.

    I make mine out of plywood and when I teach soap making, each student gets to take one home as part of the course fee.

    You can see them here at this post titled Making My Soap Box.

    1. Thanks Gavin, your's are probably bit easier for non-metalworkers to make!

  6. Oh wow!! I love them! What a fabulous idea.

  7. Great! If he wants to make more, I think you would have some keen buyers - me for a start!!

    1. Thanks, unfortunately, like most things Pete makes, it is too heavy to post....

  8. Looks great! I've been pouring mine into little individual silicon moulds, but they always go funny on the top. I really need to try it in a log.

  9. great moulds. I love that you can take them apart for easy removal of the soap.

What to do with eight acres

Behind the scenes of my blog I can see the search terms that led people to find my blog.  It can be quite interesting to look through them occasionally and see what people are looking for.  Most of them involve chicken tractors, but another question that comes up regularly is “what can you do with eight acres?” or “how much land is eight acres?”.  Today I will try to answer this question.

Of course it is a very broad question, there are lots and lots of things you can do with eight acres, but I’m going to assume that you want to live there, feed your family and maybe make a little extra money.  I make that assumption because that’s what I know about, if you want to do something else with your eight acres, you will need to look somewhere else.

If you haven’t chosen your land yet, here a few things to look for.  Focus on the things you can’t change and try to choose the best property you can find in your price range.  Look for clean water in dams, bores or wells, either on the property …

Cooking chokos (not be confused with another post about cooking chooks) has been the subject of a few questions on my blog lately, so here's some more information for you.
Chokos - also known as Chayote, christophene or christophine, cho-cho, mirliton or merleton, chuchu, Cidra, Guatila, Centinarja, Pipinola, pear squash, vegetable pear, chouchoute, güisquil, Labu Siam, Ishkus or Chowchow, Pataste, Tayota, Sayote - is a vine belonging to the Cucurbitaceae family, along with pumpkins, squash and melons, with the botanical name Sechium edule.

The choko contains a large seed, like a mango, but if you pick them small enough it is soft enough to eat.  If you leave the choko for long enough it will sprout from one end and start to grow a vine.  To grow the choko, just plant the sprouted choko a…

Making tallow soap

For some reason I've always thought that making soap seemed too hard.  For a start the number of ingredients required was confusing and all the safety warnings about using the alkali put me off.  The worst part for me was that most of the ingredients had to be purchased, and some even imported (palm oil and coconut oil), which never seemed very self-sufficient.  I can definitely see the benefits of using homemade soap instead of mass produced soap (that often contains synthetic fragrance, colour, preservatives, and has had the glycerine removed), but it seemed to me that if I was going to buy all the ingredients I may as well just buy the soap and save myself all the hassle.  For the past several years I have bought homemade soap from various market stalls and websites, and that has suited me just fine.
