Computerized methods and software for creating customized embroidery. Embodiments include capturing a drawing from a user in a browser window as captured vectors, receiving the captured vectors and desired stitching parameters at an embroidery engine on a server, and creating a planned pattern of stitches from the captured vectors and the desired stitching parameters. Some embodiments include returning a rendering of the planned pattern of stitches to the browser or returning rendering vectors to the browser for drawing the planned pattern of stitches in the browser for inspection by the user. The drawing can include a freehand drawing, handwriting, or a signature, drawn or written by the user in the browser window. The desired stitching parameters can include angle, width, underlay type, density, or pull compensation of the stitches. In some embodiments, width varies along a vector path, for instance, based on pressure applied by the user while drawing.
