Unable to get stated yarn in color I wanted hence using the Rowan. To get the right tension I used a 3.5 mm increasing to 4.5 mm on the sleeves. OK with 4.5 mm needles on body. For turtle neck used 3.5 mm increasing to 3.75 mm. Fisherman’s rib just seems to take forever which I found somewhat tedious at times. Determined to finish in next week. Yarn ok but praying it doesn’t melt into a felted mess on first wash. Delicate will be the keyword!
