craftgrrl | Lining a crocheted bag?

I´m preparing for a design market in a few weeks, and for the first time I´m thinking of selling some of my crocheted handbags. Haven´t finished the lining though... Just yarn makes them to soft, so I have to use a sturdy fabric on the inside.

The problem is, I don´t know how to sew the fabric and yarn part together in a way that both looks good and will hold. I´ve seen quite a few knitted and crocheted bags on this community, so I´d really appreciate some tips on how to go about with this. THANKS!
