So sorry to hear it and hoping it turns up too.
I once asked my son to empty my garbage bag that is in my sewing room where I throw the little scraps and threads as I sew. Didn't think any more of it but when I looked for the bag of fabric for my next project, it wasn't to be found. Yep you guessed it. A hundred dollars of fabric or more, perfectly matched for colors, gone. Arrggh.
So I kind of know how you feel but I'm sure it's even worse with a pieced top. :cry:
