I've bought quilted items and realized later that some things don't match up or the tension was off and the quilting on the underneath was loopy or a block was out of place color-wise but it doesn't change how I "feel" about them, they add to the comfort of my home and give me pleasure whenever I look at them. So embrace your mistakes, share them with the world, what's that saying, "they'll never notice if you don't bring it to their attention".
Besides, if someone is just throwing together garbage hoping to make a quick buck, you'll probably sense it.
