Er, I don't have twin girls.. they are 12 and 2. The 12 year old is a dancer; little sister is a copycat, so for Christmas I made them matching grey poodle skirts.
What do you need to make one of these puppies twirl?
Oodles of ruffles.
I used cotton layered over white net for the big sister.
Little sister already had a black net crinoline.
