They're all beautiful! My favorite would have to be the gryffindor bracelet, not because it's gryffindor, but because the colors go so well together, and I like the layout composition. (I'm not making any sense, am I? hopefully someone not me will be able to decipher my message!)
I wouldn't wear it without the belt (but I just don't like to wear things that have that shape). With a belt, I think it looks really cute. A black belt would look nice, but I kinda like the contrast between the green and the light brown.
great color choice, and you pleats and zipper look great!
they are easy to make, but they take more than just a little practice to get good at, and they take loads of time to make. that's a sweet tradition, you have a sweet boyfriend . if you want to learn how to make them, youtube has many helpful tutorials on them, you just type 'origami star' or 'how to fold paper stars', or something else to that effect
