I think it is great that so many have responed to "saving money" and way's to do it.
TipNut.com has many receipes for laundry detergent--in a liquid and in a powder form, hand soap, dishwasher, cleaning supplies and etc. Also has cleaning tips and ingredients, sewing, knitting and crochet patterns and many more.
Soapnuts works great in laundry and as a general cleaner. Will plant more trees of them this spring.
The "hoop houses" for the chickens also work great as a greenhouse. Same simple process in building. Harvey Ussery's web site also has some great ideas. His greenhouse houses his chickens, pigs, garden produce and earthworms!! A hoop house will work in the winter to even grow winter crops of produce.
Invest in a several books on "putting food by", root cellaring and etc. Many books through library to check out before ordering to make sure your money is well spent. Or maybe readers here could do a "book review" for others? I hate buying a book and then when it comes in it is not as good as I thought it might be.
The WWII war effort built buildings in a community and women met there to do canning and share ideas and etc. Why not try and utilize the local County Extension office to do the same? Or for any craft-quilting-needlearts and etc? Share ideas,swap patterns and etc. Extension offices can also schedule classes for instruction in many areas. Soil and Water Conservation dept. of many counties have a low cost tree program to help in obtaining native trees for planting and reforestation. Also programs that assist in monetary help with fencing programs and free soil conservation programs providing seeds of various plants to not only use as habitat but also seed for wild birds and tame. I plan to use this to plant "pockets" of seed for the free-range chickens.
Maybe several prople can go together to buy bred goats and then "share" the kids in the spring at birthing time. My does are bred for the spring and for an April birthing and the "kids " will be either given away or sold to someone close by to use. Nigerian goats are known for multiple births.That way I can "sort of" keep an eye on them , be available if they no longer want them and close by to "assist" if need be with any problems. But the idea of "passing it foreward" should prevail. Hoop houses also make good housing pens for animals. FarmTek will be willing to sell you a "greenhouse plastic" that will cover your hoophouse and will last for years. Or get their roll plastic and use as you need. I am sure there are other suppliers.
Canning of course is a must as well as freezing and drying of foods. I buy almost any canner at garage sales and etc. that I can. I have 6 and use them all. Extension office will also check the pressure guages for free in the fall for you. Canning of all types of meat has been done as well as veggies and fruit. Again, good books for assistance and info are valuable.
Learn to kill and butcher your own animals. Not that difficult but is an all day process and is tiring ( ok-not the youngest of the group) Excellent books are available-some out of print though for processing meat. Many women also at one time had a "canning machine" that was for metal cans. I am currently looking for info on them to buy.
So much is out there in resources and information-just "pay it foreward".
