Houndstooth. Lots and lots of houndstooth.

I bought 4m of wool-mix houndstooth from the remnant's box for £12, which was such an insanely good deal that I couldn't resist. However, I'm not really a houndstooth person, so I have no idea what to do with it. It's such a vintage-appropriate fabric, that this seemed like the place to ask. My favourite eras are 70s and 40s. Any suggestions?
