I don't have any photos yet, but I can tell you that Clara is making her crinolines from these instructions for a crinoline. They're really just a footnote to a dress pattern, and see, you can purchase the pattern as an inexpensive downloadable pdf.
You make a very simple, very short elastic-waist "skirt" that's really just a hip yoke, then gather quite a bit of stiff netting on to it for the skirt of the petticoat. Clara then adds another fully gathered ruffle around the bottom for even more volume. You can repeat the layers until you get the fullness you want.
One of her crinolines will be built on a slim, gored "short skirt" taken from a skirt pattern, closing with a short zipper, to give a slimmer hip line.
