Drysdale’s ridged tee will soon have a beloved space in your knitted wardrobe. The body is worked in one neat piece from the neck, with sleeves worked in the round after the raglan increases have been completed. (Pro tip: use different colors for your end of round and raglan markers, just to keep yourself organized.) The purl ridge pattern is a snap, just work 18 rounds of stockinette and pop in one purl round.
