I dont know how to even start. Do I add different color gels to white or mix in different color fondonts and mush them together? no clue.

I haven't tried this myself so curious to see what others have to say.

I was thinking of doing it and this is what I thought would work...First you have to think about what colors you are trying to achieve in the tie dye color... If it's multiple colors, I would color equal pieces of fondant (however many colors you are looking for) and then roll them into strips. Carefully squish them together and then roll together. I think the trick is to stay away from having to roll it out too many times as you may end up with a dark brownish mess!

Maybe practice with a small amount and see what happens? That's what I usually do before trying a new technique on an actual project cake!

Good luck!

I got some neon gels--Americolor makes them and you can get them in the cake decorating area of some grocery stores and WalMarts made by Betty Crocker.

I took the amount of white fondant I needed to cover my cake and then divided it into 5 or 6 equal portions. I then dyed each portion a different color. I rolled each color into a snake, coiled them all together, and then rolled out my piece to cover the cake.

I have only mixed different colored fondants. Seems like mixing gel colors would be a big mess.....

I just colored different colors of fondant separately, and then combined them all together to put on the cake! But don't over combine/mix...or it will just become one dull color
