I regularly get shapes (black silhouette jpegs) converted to vector and laser cut by a supplier of mine.
Each time they convert, they charge a design fee which is really costing me loads.
I was wondering if anyone can help me by telling me how I can take a simple jpeg and create a vector file from it.
The vector files my supplier show me seem to be outlines - so if I can create an outline vector of my shapes that would be great...
I just have NO idea how to achieve this

advice is very welcome.
Thanks in advance,
Matt
