The one caution is watch your costs when you make it for barter, don't skimp, just keep it in mind.
I want to point out that this is the basis of a really fine thought process.
Sometimes when we "make" something and it becomes "normal" we forget the planning, time, supplies, etc. that go into the production. It is difficult to barter for "worth" when we don't really know what something is priced at in a fair market. I know that "fair market" means what someone will pay for something, but when we become isolated from the standard sales market sometimes price suffers.
Exactly, and that is why somethings can be pricey as the work that goes into making should be compensated by the sales or barter price.
Which is why if you have 8 neighbors all growing gardens of corn, you may want to plant something different as sooner or later the market for corn will be a bit glutted..
But if you did have corn, making something like Corn Relish or even Beer would enhance the value..if costs are kept manageable.
