How To Shorten a Finished Hoop Petticoat

Plan A

Take pintucks between the bone tapes.(#1) You can let them out later if the lady gets taller.

Plan B

Take it all out of the bottom by eliminating the bottom hoop (#5). For strength, you should have two hoops the same size very close together at the bottom edge. Move #1 up next to #3. Make it the same circumference as #3.
