This was my first use of an invisible zipper and I didn't really understand the instructions so kind of messed it up (instead of it being completely invisible you can see the stitching around the sides). But that's ok--the pattern is so busy you really don't notice. Also if you look closely in the back the two sides don't line up--oops!
From cutting to finishing the skirt only took me a couple of hours--its so cute and easy I'm sure I'll make more, although maybe with a bit less volume.
I also wanted to share some better pictures of the first skirt I made:
