I finished Knitty’s Daisy sweater recently. I had to knit two sleeves in the same way (all sweaters have identical sleeves, I know!). After one sleeve is knit, I had to make sure the other sleeve is an exact replica. If I made a mistake in my first sleeve, I have to repeat that in the second one. Moreover, patterns specify sleeve length by inches rather than by rows, so I have to measure the second sleeve against the first one.
Looking at these problems, I was wondering if I can knit two sleeves at the same time. I will have to manage two balls of yarns which means yarn tangling and untangling. Other than this problem, is there a reason why I shouldn’t do this? I haven’t heard of anyone doing this before and may be there is a compelling reason for not doing this?
