Basically, you outline the flower with your icing (I used buttercream when I did it) on the cake. Pick a spot on the flower and using a moist brush gently pull the icing down and in towards the center of the flower. This is a very basic form of brush embroidery that I used on a cake in my photos. The cake you attached used multiple colors (which I have yet to do), so I can't help you there. I found a lot when I googled it though. There are great videos on youtube as well. Hope that Helps!
Thank you so much! I was going to google it, but I had no idea what to google! Thanks again!
It might be 'silk crewel embroidery' like this cake.
This one is simply piped one strand at a time. (Not my cake)
I saw that same cake the other day..LOVE it! I have it saved on my computer to try later
It looks like tube embroidery to me too. (supposed to look like crewel embroidery.) Done with a very fine tip and just piped one string at a time.
This video is very helpful!
