craftgrrl | flowing skirt help please

hi guys
I've looked in the memories for help on this and I think I more or less have figured it out but would just like confirmation I'm sort of on the right track.

I anhialate jeans at a phenomonal rate so am using them for another project :D. I'm cutting them all apart and making a skirt out of the denim attatching it all to a waistband from one of jeans. I would like the skirt to be quite full so it flares out when I turn so am thinking as I attatch the denim patches I do it in a wedge sort of shape? My main question is at the bottom do I curve it so it's all on the same level when it hangs? Sorry if that's a bit confusing I would do it just like a regular circle skirt if I wasn't doing it in a patchwork mish mash style and attaching it to an already established waistband.

Thanks for any help anyone can give :D
