Overcast by hand all the seams of the lining (three in total). To add some spice to the routine, I used red and black thread to overcast the edges.
Experimented with the waistband. Claire Shaeffer writes in her book that "only three techniques are used ...in couture for finishing the waist edges of skirts and pants: the self-fabric band, the faced band and the faced edge". For my waistband, I went for a self-fabric band. If you want to make the same one, here are the steps. I did not follow 100% the order and directions from the book, but couture techniques are meant to be improvised:

• I pinned Petersham ribbon around my waist to determine the length of the waistband. 
• Using the Petersham ribbon as interfacing, I basted it to the fashion fabric wrong side up. 

•  Right sides together, I basted the waistband to the skirt. Then I stitched it with my machine (this was the only seam which I machine stitched; all other seams were made by hand).
• I pressed the seam towards the band, folded the raw edge inside and, using fell stitches, sewed the folded edge to the seamline.
