take the best out of all input - ignore the rest. Don't ever think of comments as criticisms, as in critical, critic, bad words. Critical remarks are just opinions from other people and other people, no matter how close or not they are to you, come with a set of predefined ideas that really are their "baggage". Sometimes people who know nothing of what it takes to "create" anything, quilts - art - music - cakes - happy thoughts - anything, have some of the most petty thoughts to share with you.
For example, you might have worked like a dog on a 1000 piece quilt, and someone says: "oh, nice, but the colors are wrong." They cant tell you why or how, they just want to share they think your work is "off". Now, on the surface that may feel really harsh to you, BUT- really take a look at the colors. take a black and white picture to see if the values are too close; in black and white everything will be just a blah grey - no lites and darks. Or, check your colors against a color wheel, see if you could have changed a shade here and there. It doesnt take away from your hard work, and allows you to go forward creatively.
If you take it to heart it will eat at you and make you second guess your creative flow. sharet
