I love how it came out! I used the Solomon's knot / lover's knot for the lacy stitch pattern. I used futuregirl's Sew a Lining into a Crocheted Bag Tutorial to, well, sew the lining into the bag.
See how neatly it came out?:
The only thing I'd suggest would be to maybe add more stitches in cases where you're using bulky yarn. I noticed that where the the snaps were was facing a lot of pressure and separating from the bag, slightly. So I added some reinforcement stitching there.
I also used futuregirl's Tutorial on how to weave in the last end when working in rounds. Very seamless.
