I found this link which talks about adding pipign gel to the icing,
Also I would say make the bow first and then pipe the dots on them.
The dots in the pictures look like they are those sheets of candy you can buy here in the US. I have seen them before but im not sure what they are called. I dont think they are piped at all. Not sure how you would make your icing shiny like the candy sheets. I would probably make the bow, then pipe the dots, let it dry before i carefully assembled it.
CANDY BUTTONS! It would have bugged me all day
about 4 pictures down!
