After making a two part sleeve blocks which is traditionally for jacket sleeves, I cut down the middle of the top of they’ve down to the elbow. I then swing out the opening to create a 2.5cm rise. This new shape I draw around onto a new piece of paper to create a leg o’mutton sleeve. I will then pleat the sleeve into the sleeve head. Once I have drafted a toille, I can decide with the designer whether it needs to be bigger or smaller etc.
