Peacefulness toward self and others. Be gentle with your own hands and body, not knitting so frenectically as to injure yourself. Encourage others to do the same. Another aspect is not to get too competitive, with others obviously, but also with yourself. There's nothing wrong with enjoying a project that's not a challenge once in a while. Try not to get pulled into flame wars on your favorite net forum, no matter how strongly you feel about the topic or personalities involved, and certainly don't start them.
Truthfulness. Give credit where it's due, don't pretend you invented things you picked up in your readings, even if the sources are unknown to your audience. Be honest in any reviews that you share, don't let personality issues with the source overwhelm the things that you should be talking about, whether positively or negatively. Teach things fully and completely, putting in every detail to help others' success.
Honesty, or more exactly non-covetousness. Respect the spirit of copyrights: don't distribute others' designs as if they were your own. Take time and at least put in a significant amount of effort if you're going to re-do someone else's idea, acknowledge them in the write-up. (I did up there) Stores that sell designs they copied for free from the net fall squarely into the category that should be working on this concept. On the other hand, many struggling small stores have theft rates that rival Wal-Mart!
Moderation. Listen to your body and work within reasonable limits. Especially don't push too hard to finish a project, make softer deadlines for yourself if you must have any. If there is a deadline, make sure you realistically evaluate how much work the project will take, allowing extra time for unplanned events, and downshift to an easier one if necessary. Try not to let yourself get guilt-tripped into making presents for everyone, especially near-strangers like your co-worker's neighbor's new baby!
Detachment. Cultivate modesty about your skill and/or productivity. Teach others your tricks fully and completely when they ask, especially if you expect the same in return. Truly let go of finished presents, not using them as leverage for pulling strings, not criticizing how they're used or not or how they're washed. Remember the process is itself enjoyable, no matter how much you love the finished product.
And I would like to add my own personal rule: if it's not fun, don't do it! Just be careful not to say that in front of your teenagers. It's come back to bite me in the butt a couple of times! LOL!
