Don't let the word scare you. I'm not talking about doilies or scrap-booking. I'm talking about learning a skill that you can then pass on to other folk, either by passing on the skill itself, or by creating something useful for the folk of the community. There are a number of these skills already present in the community, like making mead. There are other options, though, like making soap, canning food, or weaving cloth, or even various metalworking for those with the tools. The sky is the limit, and many hobbies lend themselves to skilled crafting quite easily! Use your imagination, and learn a skill that interest you and that you have the capability of mastering. The chances of you becoming a master blacksmith if you live in a Philadelphia studio apartment is quite slim, but making mead or soap requires only a bit more space than a 5 gallon bucket or two. Learning to knit, or nalbinding, spinning, or weaving, all equally would be better suited for certain lifestyles.
Conversely, if you live in a rural area, why not raise some kind of animal that gives wool? Such wool can be traded to a spinner, who can trade the yarn to a nalbinder or a weaver, who can make something else, and so on? Let your skill be your currency!
Start by choosing any skill you like and are capable of. Don't worry if there is another person in the community who does the same thing, just try and take another angle at it. If you both make cheese, one may make a good cheddar, and another a good swiss. One may make a good abrasive soap, another a moisturizer, and still another laundry.
Trade a pair or two of socks made by heathen hands for a few bars of soap. Barter a bottle of mead for a quarter wheel of cheese. Get the honey for your mead, or the wool for your sweater, or the creme for your cheese, from other Heathens when possible, and barter your goods for theirs. Also, don't be afraid to accept in trade something you don't need, if you know someone else who may. If you don't nalbind, trade your soap for wool, knowing full well that you need mittens and know someone who nalbinds. Let the pool of goods be fluid! Buying your supplies is also an option, but try and support your fellow heathen first.
Teaching of crafts can be quite a community builder, also. If one Heathen knows how to make mead, and another knows how to make soap, then teach each other enough to do so on their own, and pass that knowledge along! This does not mean that you need to give away your treasured recipes or secret techniques to anyone save a personal apprentice, but teach enough that someone else can form their own formulas and techniques and be successful enough to make drinkable mead or unscented soap. However, it is also wise to not let your secrets die with you. Keep written records or teach your closest kin everything you know, so that your knowledge is not lost.
Alternatively, remember that you can "pay" for your music or language lessons with a few bricks of soap or cheese, or a case of two of mead or beer.
No two exchanges need be the same. Negotiate and come to an agreement that both parties are happy to accept. Lastly, remember that while we are trading goods and services with one another, cash is also acceptable to trade. In the end, there is nothing wrong with the good ol' american dollar! The key is to further the Heathen culture and support our Folk!
Go in Frith!
