Early in my pottery-marketing career (at a student sale) someone kindly schooled me in another form of transacting: “Artists don’t buy from each other, they trade!” she chided and grinned. And so we traded: hers for mine, mine for hers. It was right for all the right reasons.
I have now traded bunches of times. Some were as sweet and simple as that first, others not so much. I’m not often the one to suggest it, yet I usually don’t say no when a swap is proffered. That is mostly because I haven’t found a good rationale to refuse: a trade is always interesting, even if it goes awry. And every time it gets out of alignment (but never because of me! 😉 ) I get better at avoiding the pitfalls of forgetful, stingy, unskilled, or unrealistic traders, of which I have sadly met a few.
