Mircea Eliade wrote a book titled 'The Sacred And The Profane.' In this book you'll find some interesting ideas about how one person can identify an object as being sacred and another person can look upon the same object and see nothing more than what it is literally. He uses a rock as an example of this. One person could see a magical stone that was placed where it is by something divine (a hierophany), and another person will see the rock as a big hunk of sediment sitting inert.
I see my emotions, happy, sad and otherwise, when I look at an object I have knit. Yet, the person who gets that piece will likely never see those emotions. They are there, but only for me to see. I believe this is why it's difficult to be around someone when they receive something I have spent a long time working on.
Sitting under a Christmas tree, shamefully wrapped, far from where I sit to write this, lie my emotions in the form of a sweater. The happy moments, the weepy stitches, and all other emotions are right there. The white and blue and gray represent hard work, but they also represent my feelings. Gladly, when taken as a whole they convey one important feeling - love. I love the person I made that sweater for. She makes me smile and she brings butterflies to my stomach when I think of her, still.
However, when you dissect the sweater it is a myriad of emotions woven together. I suppose my point is this: we are vulnerable when we create something for someone that takes a long time. We open ourselves up to this collection of emotions, and don't look back. We do it for our own reasons. Happy Holidays, guys. And may your projects reflect who you are.
