Finished a sweater for myself with Lett Lopi on 4.5 mm needles. It has been some time since I knit with Lopi wool and this sweater renewed my love for it. I love the lightness and the warmth of it and also how it is so predictable. The wool stands up to washing so well and blooms so nicely. I do have buttons for the collar but will wear it without for a bit to see if I like it that way.
