The gal who asked said "
YOU paid thousands of dollars for that machine and you can't make me a baby quilt for my great grandaughter?"
That's right YOU did, she didn't, so YOU have the option of doing anything YOU want or not doing anything YOU don't want.
You can also say, "Yes, I paid thousands. I'll do a baby quilt. It will cost you a thousand. (if she says yes, be sure and get the money up front
)
