(NOTE: I'm going to clean up the thread a bit, removing non-game stuff. Don't be alarmed)
jmarkwar Mother had salvaged as much as she could to get your body to the point it is now. She exhausted all resources, so what you have is what you have, anything you could have used on the ship would have deprived Mother of important resources. You have enough skin to appear human from a distance, but closer inspection might reveal your bits (like if your collar was a little low)
At this point, your best bet might be to kill and skin an animal of the appropriate size, and use that skin/hide to cover Cherub. You may need to tan the hide first, to ensure it doesn't smell like rotting flesh.
There aren't any raw materials here that are worthwhile for the task at hand. You can guess that Mother sent out scavengers and they retrieved every bit of useful scrap, especially anything silicon-based. You can probably scavenge other raw materials, like some aluminum or iron, for use later. You are pretty well covered, again you'll just have to make sure you are careful about your clothing until you find the resources you need (you may have to do a [Disguise] check if someone gets close).
You can feel free to roll a few extra [Search] checks for the trip, to find any resources that would help your cause.
