In the end I covered the twisted cord (actually a bamboo and cotton blend knitting yarn) for the mast and spars with silk ribbon, which was more than slightly fiddly to achieve. There’s a collar around the mast, which, in an echo of the lifebelts, is a loop of buttonhole stitch. That was even fiddlier (is that a word? It is now!).
And Great-Grandfather’s wheelhouse has acquired a roof, made of several layers of buckram covered in silk ribbon, with buttonhole bars for the struts holding it up. That was also fiddly!
So, on to the wreath itself. That involved three different colours of silk ribbon, in two different width. I briefly considered something like the folded “leaf” shapes using wrapped parchement you sometimes see in 17th Century work, but in the end I decided I didn’t want to create anything too formal here, because it wouldn’t match the flow of the stitching. Sometimes a formal section provides a framework for everything else to clamber over, but here I felt it would create stopping-points, interrupting the eye as it moves around the piece. So the ribbons were knotted and looped and caught down in a sort of flowing chaos. White stranded silk French Knots, representing white berries, provide subtle accent and punctuation.
As you see, the wreath is now in place, with just a few white berries – white for peace.
I have quite a few more little tweaks to make, details to emphasize, maybe a bow-wave to add, but this is the original sketch brought mostly to life, and provides me with some hope that all that thinking and working will have a good result.
