OK, I tried RI, and I decided to pass on that (it is pain, and it is hard to give a details, it is fragile, and takes more time to dry etc..). FBCT works great is fast, gives more details, but not as smooth (in my case). I am going to learn chocolate transfers, and as I saw some of the cakes here on CC, the images looks very detailed and smooth. What I would like to ask is:
to purchase bunch of colored candy disks, or stick with white disks and purchase bunch of candy colors? What gives more convenience, and is maybe cheaper? I would like to know your opinion. And which transfers do you prefer??? Thank you!

i've only tried FBCT.

the only thing was, once it had been flipped onto the cake, after a while in RT, it would start to sweat. the beads of water didn't seem to evaporate & go away.

don't mean to hijack your thread ZlatkaT, but i wish someone can share how to overcome this issue.

I had the same issue, that's why I would like to try the chocolate transfers.
