I like the hydrangeas on the cake in this link (I couldn't get a direct link). If you click on floral cakes it's at the very bottom on the left. It enlarges if you click on it.
Love the look. I was thinking a rose tip, maybe. Any tips on the movement of the tip when piping the icing?
I did a video on these but it's kind of hard to see.
I used a tip 102 and without hardly moving my hand I piped the petals. I kind of piled them up but you could mound the frosting and pipe them on top
