Well, after reading all the preceding posts, I must put my 2 cents in also. I agree with the comment that this LAer has no business sense. If she is unwilling to do what the customer asks for, then she needs to refuse the job. I also agree that she seems to not be interested in learning her craft. She's only learned one thing & doesn't seem to do that really well. I am one of the LAer's listed here on the board for hire. Doesn't matter what I want...it's what you want! Suggestions are gladly given, but you don't have to take them. To answer someones question, yes, you can use different thread top & bottom, I do it all the time. Any LAer who hires out their services had best listen to their customers or they won't be in business very long. I'm truly sorry that you have had this experience. Please take the advice of others & seek out a different LAer.
