I am trying to draw a schema using Inkscape but I am not familiar with the software to make it as I am picturing it. Presently, it looks like that:
What I would like to add is a strip pattern (color #800000, rotated 45 degrees) but only in the background: meaning not entering the back potato-shaped object and stopping around the written `A' to leave it totally readable.
I have tried drawing a general box, filling it with a pattern, rotating it, moving it to another layer but I was still very far from the end result I would like to achieve.
