These I made from no pattern. The biggest thing I recall paying attention to was the bunching, all of which I did by hand. I dont recommend this, it sucks.
I made these when I was really into 1950s fashions.
I recall using the formula of making sure that each layer of the crinoline was double the next. Except Im not too fond of all that bunching around my waist, so my crinolines are relatively flat on the first layer.
To pretty up the white one, I added lace to the bottom.
They both tie at the waist instead of some sort of zipper or buckle.
