The yarn is a cone of Jamieson and Smith's Shetland Heritage Naturals* in a dark grey. It's not as thick as the jumper weight or spindrift yarn that I'm used to, but slightly heavier than a lace weight. I think the yarn on the cone is oiled for machine use - it certainly doesn't feel quite the same as it does in balls, or have the particular sheepy smell about it (though I got that in spades when I washed it). Regardless it's really lovely to knit with.
It also really needs to be blocked before you can tell exactly what you've got. I spent almost the whole time I was knitting this worried that the change in needle size was going to ruin the definition of the pattern, even more because it's quite a fuzzy wool whilst you knit with it. Turns out I needn't have worried, it's dressed up beautifully with lovely crisp definition. The increased stitch size means the difference between the 'right' and 'wrong' sides in the stockinette stitch isn't so obvious either which I count as a bonus.
The Heritage yarn is still fine enough to make a really light shawl, which is perfect for the current weather we're having. It's soft, warm, and drapes really nicely. I used a spindrift in a blue colour for the last 3 rows and like the slight change in weight there as well.
I love this grey colour, which is perhaps the only problem with this shawl - shade wise it's close to a lot of the clothes I wear and so likely to get lost a bit - though calling that a problem is a bit of a stretch.
I'm quite tempted to start a third Ishbel, it's a satisfying pattern to knit, easy without being boring, and everything else I've queued up is going to demand more concentration than I feel like giving at the moment.
The pattern is by Ysolda and a good place for relative beginners to lace/openwork wanting to tackle something interesting.
*£33 for a 500g cone rather than £3.30 for a 25g ball is a bargain.
