I dabble in various crafting areas and post some of the outputs here. Some of the tools I use to develop patterns for crafting (mostly cross-stitching):
As a software engineer I am utilizing some of my knowledge to build tools (e.g. pyxstitch) but, of note, cross-stitch patterns are a prime candidate for reverse engineering. If you find a completed pattern/image (and the size is reasonable) you can create a pattern if it is not available for purchase, download, etc.
