You know you're obsessed with crafting when: you see a cute skirt in the store and think "ohhh! I totally gotta get some nice fabric and make one like that" - True story.
For the upcoming New Year party, I made myself a silky, shiny, gorgeous bubble skirt! And it only took a couple of hours! I honestly think it came out way better than what I saw in the store but, as I have no photo to compare, you'll just have to take my word for it

I found a lot of different tutorials and how-to's for bubble skirts, the idea I ended up using, however,(there was no one tutorial that I used, but rather a mix of several) was fashioning the skirt out of a straight skirt and a circle skirt.
For this I used:
-A wide elastic belt
-A bit of old shirt to make the straight skirt (any stretchy fabric works)
-About 1.5 m of silky gold fabric
Step 1: Sew the elastic into a belt that sits comfortably, wherever you want it to sit (ideally hips?)
Step 2: Sew the straight skirt onto the edge of the belt (the side it's sewn on will become the inside of your skirt)
Note: the skirt should be about 10 cm bellow the desired length
Step 3: Cut out a doughnut for the circle skirt (the hole being about 10cm larger in circumference than the belt is). To do so, fold fabric into two and then two again, draw an arc 1/4 of the desired circumference and from there measure the desired length of the skirt + 20cm.

Step 4: Gather the top of the circle skirt: sew a simple stitch by hand and then pull at the string till it's the same width as the belt. Stick or pin the skirt onto the belt before sewing it on with the machine, making sure that the gathering is uniform. The skirt should be sewn on right side of fabric to right side of belt, but upside down, so that when you lower it, the stitches are hidden.

Step 5: Now that you have a pretty circle skirt and a straight skirt underneath, it's time to put them together to make the magic happen. As you did with the top of the circle skirt, gather the bottom hem. At the same time, you can fold the edge under 1~1.5 cm to hide the raw part. Mind you, it will gather a LOT more than it did on the top.

Step 6: Spread out the gatherings, pin the edge of the circle skirt to the edge of the straight skirt, and sew on with a zig-zag stitch. Voila! Admire the flow-y effect of your new bubble skirt!
Here is a shot of it inside out, so you can get a better idea of how it's made (I hope the writing is legible!)

I hope the instructions are helpful! It's a combination of others' instructions, my mom's tips and my own logic/learning by doing experience.
And of course, the model shot! (Now just to find/make a nicer shirt... hmmm)

Thanks for looking! =D
