Some additional notes:
The scale had both metric and ounces measurements.
My apologies for the not up to par pictures. I'm at least getting better about taking some pictures.
About the key covers... A couple of them I felted the top hem, but the others I ironed on some interfacing or iron-on patch fabric at the top where the cord goes through. I had thought initially of pinking each side individually, but then found I could run it through my Singer hand crank pinker after it was stitched together (two layers).
For the handkerchiefs I stitched them on a 1949 15K90 with 35996 (5/64") hemmer foot. I have heard about the narrow hemmers being different even though they are for low shank machines. I realized that the recommended narrow hemmers for the different machines is based on the direction the flat of the needle is inserted. I did try another foot for 1/8" hem and didn't see much of a difference in width of the hem, but the stitches seemed to be a little closer to the outside edge.
