invitation questions...

Okay...
So, I've been at it again.

I designed some wedding invitations for a friend's friend.
She loved them, and asked me to send her a proof. I saved the lowest possible pdf size I could and emailed it to her.

Problem #1: We never agreed on a price ahead of time.
Problem #2: She took my design, and is using it throughout her wedding.
Problem #3: She thinks $125 (which is a fraction of what I normally charge) is too high, for the design (even after admitting she is using this design throughout different items, including her wedding gifts)

She wanted custom work...for a 'kit' price.
I don't know how to respond.

She took the file I gave her to a friend, who is going to print them for her...and was like, "That's okay, right?"
(I should've watermarked it...I KNOW)

*rant*
I'm just having one of those, "Why do you think I spent $20,000 on a degree to make you $50 invitations. I'm not in college any more!"
Okay *rant off*

Help!...What's the best way to tell her, that what she did was wrong? or do I just wait until she pays me whatever she's going to pay me and tell her, "Never do business like that again."

I guess I'm just really worried about her not paying if I say something now and what my recourse would be if she didn't.

I really want to tell her that if she can't pay that, then I'll have to ask her not to use the design...but I don't know what to do if she does use the design, and just doesn't pay me.

Her total budget for design, print & postage is $150. (just found that out)
I want to be like, "Are you f**king kidding me? You couldn't get invitation 'print-at-home' kits and mail them for that price?"

Yeah, the original plan was to meet and get some ideas for what she wanted. I have a creative brief that I asked her to fill out. (although, she only filled in a few fields)...On this creative brief there was a place for 'agreed upon pricing'. (but somehow this never came up)

I had a good idea for what she wanted, so threw together a comp...never intending her to LOVE it, but just so she could see their names on paper.
(obviously this was a bad idea).

I really want to put my foot down and be slightly catty about it...but I could see where I would have the upper hand by gracefully 'bowing out'

After all is said and done, is there still reason to lecture her on how good business is really done. The girl is still in college, and from what I've heard from my friend is obnoxious in her personal life (stepping on toes, and inviting herself places). It sounds like this is how she takes life in every aspect of the word...and somehow I think she needs to hear the brunt of it sooner than later. (Although, I'm not one to ruin someone's wedding experience...I remember how stressful that was.)

Oh, well...thanks for the feedback everyone.

Okay...Here's what I want to say. Is it fair?

"Okay, so I've had time to sleep on it, and have asked other designers in the field what the best way to handle this situation would be.

The better way to approach pricing would have been to ask you what you thought my custom work and time was worth before we started...and if wasn't a match, then we could have discussed further how we wanted to move forward.

I realize now, that my pricing (even though severely discounted)
may be (and have been) slightly out of reach. You decide what it's worth to you...and then we'll talk more about it.

I do want to point out that the pdf I sent you was the lowest quality I could save it as...If you would like a highres pdf let me know. I don't want something out there with my name on it, printed in low res (it may look fine to you...but it most definitely wasn't print ready).

There's more.
Sure I designed the invitation. But it really hurt my feelings that you took the design and had someone else finish the project without my knowledge of you doing so. When you left from our meeting, I had no reason to believe that I wasn't finishing the design for your wedding ensemble. You even messaged me asking to design thank you's as well. (I am assuming you're just going to have your friend do those as well)

Everything is all over the place.
I don't want to upset you because I know how stressful planning a wedding can be. I just wanted to point out that when (in the future) you ask for custom design work...keep in mind that a designer's time is going to cost more than something you can buy in a store, because of the simple fact that nobody else will have it. I also don't want to offend you when I post the design up to sell to other people now, to help recoup my costs (I wanted to let you know ahead of time)."

She b*tched out...because she found me through a friend, she wanted a 'handout.' She said she's not going to use the design, since she hasn't paid for anything. But I'm going to keep my eye out, I just don't trust her.

She called and blessed out the friend who tried to set this up for us (because when 'friend' tried to reason with 'bride', she was accused of taking sides)...and I think 'bride' is trying to kick her out of the wedding now too.

This is BRIDEZILLA if I've ever seen it.

I dipped out of this drama, asap.
...and don't plan on making this a reoccurrence.

Update:
She had a local printer use clipart...CLIPART for the artwork on her wedding invitations. (I just hope there wasn't certain copyright issues against that kind of usage).

Oh, well...just thought I'd let the creative world know how much, the rest of the world just doesn't understand.
