I agree with Feline fanatic. You shouldn't be the only one learning a lesson here. If your customer had a price limit, she should have let you know. Neither one of you is any more to fault than the other. I'd ask for 87.20.

Start high and negotiate down. 40 - 50 $ is way too little for all the work you did!

No, not to much. But even though it was hard, you did a beautiful job and you learned a lot!!

Did she make the quilt? If so, she should understand the value of your time. If not, she has no clue. You can be the educator, but remember you represent quilters everywhere when you charge what it's truly worth in skill and time.

Love your work! I would tell her $100, then negotiate the price down to $85. (Even loves a bargain!)

Your Quilting is just stunning. When you take something in like this, You can ask what is your budget? Then you can say that will be fine your tell her it will be so much more.

I would go with one of these higher amounts recommended here instead of your initial $40-$50, and maybe take a bit off if she balks. I would worry that if you give a lower price initially, that would become your "standard rate" and she might send more business your way thinking it's always going to be that price. Probably better to have one misunderstanding now than many misunderstandings in the future

There is a lesson to be learned in this situation- have the terms and conditions agreed to and written down beforehand. One fact is obvious to me. you didn't know what you were going to be up against before you started on this project so you would not have been prepared to state a really fair price. Your quilting is beautiful. However, this time you made need to accept less than some of the board members think you should charge because you were inexperienced. I did drapery fabrication for a number of years and in the early days I endured less profit for time spent because of inexperience in pricing as opposed to inability to produce a quality product. Good luck as you talk to your customer and I hope you reach a mutually acceptable price.

Wow beautiful. I can't believe you can do such beautiful work on a DSM, its wonderful.
I know nothing abt. charging but I can see how much work is in this project. don't sell yourself short.

The last time I checked around here, quilting starts at $0.02 per square inch. Binding is extra. I would charge at least $75.
