--- title: "@freesewing/plugin-bartack" --- The **@freesewing/plugin-bartack** plugin provides [the bartack macro](/reference/api/macros/bartack). This macro allows you to add bartacks — a set of tight zig-zag stitches used to enforce a seam — to your design. ## Example Example of the bartack macro provided by this plugin ## Installation ```sh npm install @freesewing/plugin-bartack ``` ## Usage Like all [build-time plugins](/guides/plugins/types-of-plugins#build-time-plugins), you load them by passing them to the [freesewing.Design](/reference/api/design) super-constructor: ```js import freesewing from "@freesewing/core"; import bartack from "@freesewing/plugin-bartack"; import config from "../config"; const Pattern = new freesewing.Design(config, bartack); ``` Now you can use the [bartack](/reference/api/macros/bartack/), [bartackAlong](/reference/api/macros/bartackalong/), and [bartackFractionAlong](/reference/api/macros/bartackfractionalong/) macros in your parts.
