Last week I tried out some Mulberry silks which I’d had in my stash for some time, to see how well they were suited to Hardanger. The Thick and Medium silks I tried first were both a little on the chunky side compared to #5 and #8 perle cottons. I don’t mind that so much for the Kloster blocks, where good solid coverage is a bit of a bonus to my mind, but if you’re going to use the thinner thread for backstitch as well as worked bars and filling stitches it can look better when it’s a bit thinner than a #8. On the other hand, too thin and you end up having to work an endless amount of weaves or wraps to give your worked bars decent coverage.
I intended to try out Mulberry’s Thin silk as a substitute for Medium, but just looking at it on the bobbin made it quite clear that it was going to be far too thin. Mulberry give the thickness of their threads in the x/y format which I’m still trying to get my head round. It means, as far as I’ve been able to work out, that the thread consists of y number of plies, and each ply has the thickness x, where a higher x means a thinner thread. Apparently it’s all based on the number of 840-yard hanks you get from a pound of thread. I assume that’s an imperial rather than a metric pound, but whichever it is, after about ten seconds of trying to work this out my eyes start to glaze over and I decide that I can spend the time much more enjoyably stitching.
It boils down to this – as with perle cottons, the higher the number the thinner the thread. And a 30/3 thread is equivalent in thickness to a 20/2 thread, although I’m sure it makes a difference whether it is, for example, very tightly twisted. Anyway, Mulberry Silks’ Thick silk is a 10/3, Medium is a 30/3 and Fine a 100/3. So the trick would be to find something between 30 and 100. Enter their Quilting silk, which is a 70/3.
The Quilting silk is lovely for the little backstitch motifs, with a very nice shine and crisp detail,and it makes a beautifully lacy square filet, but it is quite thin for the woven bars and takes a lot of weaving to get good coverage. Probably the best solution would be to use Thick for Kloster blocks, Medium for bars, and Quilting for filling stitches and backstitch.
Yesterday the postman brought me some lovely Treenway silks to add to my collection – watch this space for a further silk Hardanger experiment!
