Remember back when the lunch boxes had the pocket on the top? (I must admit I still have several originals in my mint. Retired Colors Museum!) Before I purchased my Fast Frames system, I used to have the darnedest time stitching on them. Sewing through the two layers of nylon and the insulated lining caused the thread to loop on top of the bag, giving the embroidery a hairy appearance--I don't know about you, but I don't do hair. I was very excited when Christi decided to lose the pocket, but was suprised to learn that not everyone felt that way.
