I did this embroidery ages ago but only washed the stabiliser off last night (so that was the first time I could see if it turned out OK). Relieved it turned out well! If you look at the close-up you can see there are a few places where my “doing in the ends” came through to the good side by mistake, but I’m not too bothered by that.
The fabric is a viscose/cotton mix bought from Cloth House, the thread is silk floss from Pipers Silks, and the embroidery pattern is lace stitch from the RSN Stitchbank.

I call this “fake blackwork” because the stitch pattern is a blackwork pattern but I’ve done it on a grid that curves around the neckline, whereas (as far as I know) real blackwork is always done on a strictly square grid. I made the curved grid in Inkscape using two techniques: repeated “inset” of the neckline path for the curved lines, and then “pattern along path” using a repeated straight line segment for the spokes. I printed the grid onto soluble stabiliser and then stitched over it.
