The halter is knit in the round from the bottom up. Stitches are picked up from an I-cord. The front is worked in 2x2 rib and the back is worked in a lace pattern. I-cord is attached at the front neck and lies over the shoulders. It is threaded through a tube at the top of the back and tied, creating adjustable straps.

Only two sizes are offered in this pattern. The Lace Butterfly panel pattern used in this design requires 10 stitches. Pattern multiples were spaced a few stitches apart to create the stair step effect of the lace on the halter back. Adding a stair step meant adding a pattern multiple to each side of the back, and because the multiple is a large number of stitches, the width of the back is increased from a small to a large size.
