Wow, how beautiful! I love the pattern you created and the shape of the skirt is beautiful. And the color combinations are very unique. You can always wear it as a costume or a ball gown.
I made two very similar skirts and a top just last year. A little tiring to sew but well worth it. My method of construction evolved: I started out accordion-folding ~4 inch strips of fabric then cutting out triangles. Once you unfolded it, there was the long strip with the jagged edge! But it created too many small triangles that I have been struggling to find uses for. Then I realized I could fold ~6 inch strips and use my rotary cutter in a large zig-zag pattern so I would end up with two strips and no scrap. I then added the strips to an old skirt and top. I can see how using scraps would get difficult since you may not have long strips to work with. And the size can range dramatically. No need to finish the edges, especially if going for the faerie look. I intend on making many more of these items. I am currently working on a purple one for my mother-in-law!
