You have two options with Carbide Create:
- place the images on the background and re-draw them
- use the 3D features in Carbide Create Pro and cut them as 3D textures
Alternately, you can trace or re-draw them in a 3rd part tool such as Inkscape: How to Trace an Image Using Inkscape: 14 Steps (with Pictures)
If you’d post a file we’ll gladly help.
