While I agree that there are those who do not appreciate our efforts in this art form we all love, the appreciation is not the motivation for doing it.
I discovered years ago that hand crafted items (be it quilted or painted or embroidered or whatever other) are appreciated by some but not all and rarely sell for an appropriate $ amount in relation to time spent.
Has that stopped me from doing the creative projects that I love? Not at all! I just don't do them to sell, I do them for my own satisfaction.
And when I donate items to be raffled or auctioned I don't ask how much my item sold for, only how much was raised total. And I only send small items as I've seen that often they raise more proportionally than something big.
