Help with lining a purse

I’m looking for any how to sites to help with the lining part. I am not
good at this crafty stuff. It’s as if I’m suppose to already know how
to do this. I mean I know I’m suppose to cut fabric to size and sew
and one pattern says to sew so the stitches are invisable. How the
BLEEP can stitches be invisable? How does one sew the lining so
it doesn’t have an ugly edge to it?

I love this forum, I could spend hours at a time reading all the ?'s and A’s.

Does this help any? http://www.helloknitty.com/pdfs/Lining.pdf

Here are the hand stitching instructions they refer to: http://www.helloknitty.com/pdfs/Handstitches.pdf

They have other help files: http://www.helloknitty.com/videoinstr.htm I haven’t watched the videos (I don’t use Real Player), but the links on the right are good, like how to put in a magnetic snap.
