Your own 3D parametric modeler.
FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters.

It sounds like you are looking for more of a pattern designing tool. There are open source projects that might be more suited to this than freeCAD. Try searching online for “open source textile pattern software”
I can’t vouch for this program/project as I am not involved nor have I used it; but Velentina sounds like it is capable of doing what you mentioned.
The sketchers in freeCAD can be used to draw and constrain the patterns, and then print them to scale and cut them out to see how it works.
(Note I have not tried to print to scale from freeCAD specifically but I would imagine it is more then capable of doing so assuming your sketches are smaller then the paper you are printing on)
Of course freeCAD can be used to do the physical modeling but I am unaware of any tools that would specifically assist you for textile pattern designs. The closest tool that I am aware of is the sheet metal workbench.
Hopefully this was helpful.
Someone else might be able to suggest a freeCAD specific solution but this might help get you started.
