Just finished blocking a vest I made using Shetland wool that was left over from other projects. I used a 3.25 mm needle. It was knitted in the round with steeks for the the front and arm holes. I didn't bother securing stitches but just cut the steeks open and picked up stitches for the border. It was a fun and fast knit. I used the Fibonacci Sequence and made a sort of bell curve with 8, 5, 3, 2, 1, 2, 3, 5, 8. ......
Sorry the before cutting picture is blurry.
