The pattern is a free one available on Ravelry and is by Jane Tanner (Knit Jane Knit). It is extremely well written with easy to follow charts and knits up quickly....even for me. Mistakes are easy to spot as the pattern has a nice logical flow to it.
I used 4mm Birch straights moving onto a 4mm circs when stitch numbers needed it. It took 1.5 50g balls of Rowan 4ply Soft which is a 100% Merino wool. The picture above is the truest to the colour.
Would make this again and probably again. I made the smaller one but it is easy to enlarge and she gives guide lines to this in her pattern notes.
I love it.
