The Allegro sleeves are worked flat and then seamed along the top portion of the hand and arm. Basic stitches and a beautiful yarn get the job done nicely.
The yarn I used for the sample knit was handspun by a local fiber friend. It is a thick and thin single spun wool that falls into DK weight. In the materials box below I have given yardage estimates and also provided a few other yarn options that I feel would work for the style of these sleeves. Of course, do feel free to switch it up and use your favorite yarns.
