i would like to know how to do the above flower and also should i use the piping gel also to do it and secondly with wut consistancy should i do that and how many days before in hand if i want that to be present on wednesday evening.

You could use a small rose tip, royal icing and a small flower nail. Instead of bringing the petals up and around like a rose, pipe five petals flat. You'd need to give them time to dry so they'd have to be made at least a day in advance.

You could also make them from fondant using the forget-me-not cutter.
