Just started and cast on both legs to knit at the same time.

Decided to put in the zipper without the little knitted edging in the pattern. Came out really nice with the invisible zipper:)

I knitted both sleeves at the same time . The hardest part was the small pattern at the cuffs. They are mirror opposites. I marked one sleeve as right so I would be able to distinguish the pattern needed for each sleeve and kept the marker attached till I sewed in the sleeves.
