As promised in an earlier post, here is a picture of the Victorian Pin Cushion that I purchased at the world's cleanest antique store.
If you look closely at the pegs on the bottom, you will see that the one just to the left of centre is slightly larger around, and a different shape from the others. I'm guessing it's the spot for your thimble.
And after the little pushes that I received from friends in my last post, I went into my sewing room and did a little sewing today. Thank you to all for your suggestions - I'll do my best. :-)
