Don't let quilting become a power struggle....."no, I can out give YOU"!.....allow this couple their blessing.
Obviously their heart intent is to bless you, and for the giving they are blessed in return.
Graciously accept whatever they offer and, without explanation, put it toward a class, as suggested by Karen, to improve your skills so you might be in position to earn further monies for skill. They will consider it seed planed in good soil. :-)
