Just in case anyone missed my happy ending, I did find my pattern. It was at my sister's house...where I left it when I was asking for fabric ideas.
So, happy ending. I have to admit, I had not looked in the freezer or on top of the refrigerator, as two of you suggested. I will certainly look in those places the next time I can't find anything. :)
Thanks for all your suggestions and comments that made me feel much less grumpy!!
