For my costume, I used a yellow/gold fabric. Draw out your designs (using a curved ruler really helps make them look sharp and crisp). Use some heat-n-bond (you can find it at any craft store, normally by all the interfacing). Cut out your design, then iron it onto your quipao. Do a top stitch about 1/8 to 1/16 from the outer edges of your design and you're finished. You could also do a satin stitch around the edges. Of course, put on the design before you sew the quipao together. For the edging around the neckline, hem, etc. you can use piping if you're feeling especially ambitious, or make some bias trimming.
I made my bracelets with spikes like this
. They're guaranteed to be nice and uniform looking, easily replaceable, and available in varying shapes and sizes.
