After searching and searching I finally found the bag.
That was followed by another obsessive search for an appropriate picnic blanket which has now been located.
Then began the hunt for this aqua vintage style thermos. They have been discontinued and I'm told the remaining stock was sold to HomeGoods. Being the sort of person you know me to be, I'm sure you have guessed that I have been to every HomeGoods in my area. And just in case, every TJ Maxx. And every Marshalls. And nothing. So I'm putting out an A.P.B. to all of you my dear friends. If you can get your hands on this totally Jen style thermos, I will make it worth your while.
UPDATE: THE THERMOS WAS LOCATED, BOUGHT AND SHIPPED. I RECEIVED IT YESTERDAY! YIPPEE!!!!!!!!
