Urgent: Inflated textile/ fabric

I want to create a self-supporting arch (vault) fabric/textile structure. The idea is to sew the fabric and fill it with agricultural waste and mycelium. Stitches form a pattern on the textile structure, and there is a hole in the middle, as shown in the attached images.

Reference: Mycoskin


I appreciate any help, as I am new to Rhino Grasshopper.
Thank you.

First things first. Turn the computer off and break out the pad and pen.

Sketch a concept.

Then show that to whoever is going to be making the item. Once you have worked out how an unsupported non-tensile arch will stand up (good luck with that) then you can think of modelling it.

Remember, Rhino and grasshopper are design tools - they don’t magically make the unmakeable into a real item.
