Stockings

I can't believe I'm going to admit this, but my sister's stocking has been sitting in the exact same basket for the last couple of years. I stitched all the way to the toe, and now I am reluctant to finish it up and sew in the ends! What's really holding me up is that I don't know how to sew in a lining, and I'm freaking out about it. I have a purse I've basically completed except for the lining! Someone help!!!
