Pellucid is a simple top with sheer striping, created by alternating between one and two strands of lace weight yarn.
It is designed to fit loosely, with around 10 cm / 4 inches of positive ease.
Worked top down, sts are cast on for the neckline and shoulders. Front and back are worked flat, then joined in the round for the remainder of the body when sleeves are created by grafting a number of sts from the back and front together.
Explanations and instructions are given throughout the pattern, and links are given to handy resources.
