Several people have asked me how I line my purses so I took some pictures as a lined one.
Hope it helps. Any clarifications needed, just drop me a line.
Here's the purse I'm going to line.
Fold lining material in half and with fold on bottom. lay purse area to be lined on top. Top of folded area should be about 1/2" above top of purse.
Measure approximately 1/2 " on each side of purse and cut across top and down both sides. 
Sew each side with an approximate 1/2" seam.
Press seams open on both sides.
Make box corners at the bottom corners of the lining by sewing across each seam. The stitch line should be approximately the same length as the depth of the purse.
Clip corner to approximately 1/4".
Lining should start to look like a box.
Turn down top edge approximately 1/2" and press.
Drop lining inside purse as is (wrong sides facing each other) and ease to fit. Pin in place approximately 1/4 to 1/2" from top of front of purse. Make sure back of lining and purse are laying straight when pinned in place.
Top stitch in place close to pressed edge.
Finished edge.
Stitched seam of lining blends into crocheted stitches.
All Done!!!!
