/cgl/ - Cosplay & EGL

thinking about making sucrose from genshin impact. i have a few ideas for the smaller details like the stripes and designs on the cape/jacket but im not sure if theyre the best way to go about it.
for most of the designs i could make appliques out of fabric and iron them on with heatnbond, but im afraid of the edges fraying. i could do a satin stitch to prevent this but it looks kind of bulky?
for the stripes im not sure if it would be better to use ribbon or bias tape. i want to avoid having to paint anything onto the fabric, but if thats the best option then ¯\_(ツ)_/¯
any suggestions would be appreciated!
