anyhow, the one i bought was a metal piping nozzle and the disposable piping bag. then just push the icing out and do swirlies. hehe. i'm sorry. i know that does not seem helpful. but i do that. uhm, i guess if you're baking normal size cupcakes, you'd need a bigger star nozzle. makes the design bigger. but i do mini-sized ones. i'm sure you could still ice a normal-sized cupcakes with a small nozzle, it's just a matter of extra work. but it's fun!
i hope i helped you there.
question though... what icing are you using?
personally, i love the slap-on icing style. y'know, yang antam saja tia. and it's just there on top of the cake. it gives out a feeling of it being homemade. hehe.
now. i did this for sabine. i swear, she is a DARLING! d-a-r-l-i-n-g! MAJOR DARLING! haha. was gonna go for something halloweeny but i failed fantastically. yeap. i don't even know what it is! by the way, be sure to check out her blog if you wanna see me without makeup, and ugly hair. haha. inda sampat berusai tadi ba!
see, when i bake. i always make extra two pieces for me'self, see. and i just ADORE my orange swiss meringue buttercream icing. haha. nyaman jua. hee.
