Bonded fabric

I keep seeing bonded fabrics around. What kind of projects would these be really good for? I'm fascinated by the idea of 'two-for-one' and how you might be able to use it without lining. I guess on a basic level it might just remove the need for a lining. I'm interested in what could be done with it, I'd love to hear ideas! http://www.topfabric.co.uk/fabric/wool-tartan-bonded-with-red-nylon-19156.html http://www.topfabric.co.uk/fabric/chunky-wool-knit-bonded-jersey-grey-black.html
