Take object 1 (above photo) - ripped lining inside nephews parka (raincoat if you prefer).
How do you fix that strange synthetic slippery frayed lining stuff?
I had absolutely no idea - I couldn't use anything that was iron on as I was afraid that I would just melt the entire lining onto the iron, so my best and most creative solution, was to cover all of the frayed edges with some homemade bias binding......
.... and then handstitch the bias binding together to close the gap.
At least he can now easily identify which parka is his, just by looking inside!
