The construction of the basic box in which the Jack sits was by now familiar, so I got that bit done and gathered the box, the lid, its lining and the loop to hold the emery.
I was worried that the very fine emery would leak out, so I stitched the bundle of emery closed in a vigorous, if inelegant manner before attaching the ring.
The fiddliest bit was attaching the ribbon to the spring, but it worked OK.
In the end, the 'push' on the lid is quite strong against the bead catch, but it holds, and works.
And the lid? - Looks better than I had hoped, a testament to the hours of work in those petit point lines!
So, the Etui is finished. Here are a couple of photos of the finished pieces, both inside and outside the box.
