If it is for charity or very simple quilting, I will go as little as a penny a square inch. Most of the time it is 1 1/2 cents per square inch for what I call mindful meandering, which is freehand quilting. You really can't go wrong on that. I do charge about $3-5 for thread depending how close it is stitched. I only use the Egyptian top thread and bottom line bottom thread which are very expensive but my machine doesn't get linty with them. It isn't the whole cost of the thread but nobody has complained about it.
