Is this something that you still use? Or is there better ideas out now? The reason I ask is because I am still new to decorating and have been reading a lot of OLD Wilton yearbooks. They talk alot about color flow but I was wondering if this technique is still used much or have you progressed to other things! 
Thanks!
This techinque is still taught in the Wilton classes so I would say yes it is still used. It is not the only way to put an image on a cake with out having to do stars, but it is still on the list. 
This is a great thing to do if you need/want to do part of the cake ahead of time as it needs to dry. You can also use this for figures to stand up on the side of the cake or top of the cake.
I am also new, and been trying different kinds of media/materials. I really enjoyed working with fondant, but I found colorflow/royal icing has its place in cake decorating. Please check my Nemo cake and Black dragon, in both I was using RI(=color flow) and I was happy with the results.
alwayscake your cakes are great! Doesn't RI dry very hard? Is it the same as colorflow? What recipe do you use for the RI that you used?
Yes royal icing does dry hard. So does color flow. Wilton makes the color flow mix and according to them it will make a stronger and more shiny piece.
I have used royal icing for about 95% of the 'color flow' pieces with no problem. You can dry it under a desk lamp to help add shine to the royal icing.
I use Wilton's recipe for it.
Whenever I use color flow I always dilute RI, because according to my Wilton teacher the only reason to use Wilton's color flow mix is because you bought it with the course 2 kit. It's just a waste of money and time because diluted RI works just as well.
Thats interesting to know. I just always bought the color flow mix because I thought I was supposed to...Like it ws the whole "secret" to color flow.
Nope, as long as the RI is diluted enough so that it flows out of the bag without any pressure and still has enough body that it won't overflow the piping it works just the same and it is still glossy.
