This is a “Jack O’Lantern” sleeve draft, I thought if I used only the upper sleeve I would create the desired effect.
I started out with a 10″ long sleeve, and trimmed it shorter as I worked. First I trimmed off 1″ at the hem on each side, tapering to nothing. I also rounded out the bottom edge. I wasn’t sure how much to do that, so I’m learning by trial and error.
Then I divided it into eight sections vertically. The simplest way seemed to fold it in half thrice and trace my fold lines.
Next, time to slash those lines. I was a lazy monkey and left the seam allowances, so I had to make hinges.
Starting with section A and using the diagram as a guide, I taped each piece to the table, arranging the sections as best I could to form a circle. I could have tried harder.
Slipped another piece of polytrace over the top. At this point I felt completely lost. Should I connect the sections with a straight line and then round them out? Should I use my curve tools? In the end I used my curve, slowly working around the circle. I feel like I’m making piles of beginner drafting mistakes, I wish I could take a basics class.
It occurred to me to fold the piece in half, with the shoulder seam as the midpoint, and trim down the edges so they would hang evenly when I wear it. I toyed with the idea of folding it into little eighths to get a perfect circle (like when you prepare to cut a snowflake), but decided against it. In retrospect, this would have solved my un even hemline problems.
Finished sleeve. I barely fit it on the fabric left over from cutting the shirt body, I did have to cheat a little. I didn’t bother too much about grain, I figured it would be fine cut on the bias. Does knit have a bias? I sewed the side seams and then attached the sleeve much like a set-in sleeve. I left the edges raw because all my sneaky shopping shows me that knit flutter sleeves have raw edges. I think if I hemmed, it would weigh down the sleeves and I would lose some of the movement. Should I leave the “asymmetrical” edge on the sleeves, or trim them down?
