Halter top is written in one size, but can be adjusted slightly by using other hook sizes or adding/subtracting stitch pattern repeats. Pattern was created using Red Heart Super Saver worsted, but cotton worsted could work as well. This halter is designed as a novelty to go with the popular mermaid tails to complete the mermaid fantasy. Pattern only includes the halter top instructions,although a picture of how it looks next to a matching tail and headband is shown for clarity of description. Many pictures are included in pattern to assist with creating the mermaid halter top.
