The cable in this pattern reminded me of the diamond-shaped mullioned windows in Tudor-era palaces in England, like Hampton Court and Greenwich. This round-neck, raglan-sleeved top is a companion to the Tudor Windows Cardigan. It is shown as short sleeves, but instructions are included for any sleeve length.

Yarn: Space Cadet Lyra (100% Superwash Merino wool, 270 yards/100), 3(3, 3, 4, 6, 6) skeins as shown. Long sleeves will require 4(4, 4, 5, 6, 6) skeins. Sample worked in Yes, Dear.
