Flounces on your hooped petticoats will save you from the Heartbreak of VHL (Visible Hoop Line.)
Ruffled sheets and bedskirts are a great time saver, and are conviently pre-gathered. Best to keep to a plain white/cream/ecru color, since other colors will show through.
And if anyone comments on the origin of your hoop, you may slap them... because if they can see your crinolines, they are TOO CLOSE.
