This was an easy knit. This is a free pattern from Ravely "Larch, by Tinks and Frogs Rue, from tinksandfrogs http://www.ravelry.com/patterns/library/larch
Old Shale is a classic Shetland stitch. The only difficulty encountered in this pattern was the increase in pattern repeat but once I realized where I was going wrong it all fell into place nicely.
I have knitted this for my cousin whose 40th birthday has just gone. She may need it as she and her partner have just returned from Antigua on a celebratory trip.
