This happened to me 2 years ago... We went to Myrtle Beach for Christmas. I packed a pattern and all of the fabrics I collected over the course of 18 month to cut if I had time... I didn't. I KNOW I put it in my son's suitcase when I was packing.... When I arrived home it was no where to be found. I checked the hotel room mutiple times before we left so I don't think it got left behind....
I put off calling the hotel in the hopes it would turn up.... It never did.
So I have started buying fabric again. This time I am keeping track of it.
