1. trace out your pattern (I just used a pen instead of chalk, but if you aren't as accurate a sewer use chalk because the pen will show through)
2. sew along your pattern
3. cut little slits to make inverting easier for the fabric
4. invert your piece
Depending on how your outfit looks:
5. I top-stitched the piece (to kind of shut it up and also matches the look according to my reference)
6. then sewed the piece onto the base fabric
I need to go buy the fabric for the band, so the hat will remain unfinished for a while, just like the skirt.
