There’s gotta be software out there that will do it for you.

Try using Inkscape https://inkscape.org . It’s an easy to use piece of software that will allow you to produce a digital image from a photograph. It’s free!

I would suggest you use photo editing software like Photoshop or Gimp and do some editing on your image. You can crop, rotate, remove unwanted objects from your image and then save it in PNG format. If you are not familiar with these terms, you can search for tutorials on the internet and learn how to do it. I also suggest you https://masterbundles.com/graphics/patterns/stripe/ source to download stripe related graphics. I would also suggest that you work with someone who knows how to use these programs and has experience working with wood. If you don’t know what you’re doing, it’s very easy to mess up an image and end up with something that doesn’t look right when cut in wood.

If you are only planning to do one CNC machine design, maybe you need to commission a rellef wood carver.
