For woodgrain should I start with brown fondant or just paint white fondant brown and try to streak it a lot?
I would start with brown fondant, then use some (darker) brown gel with your vodka and paint on with a fan brush to give that "wood grained" effect. HTH.
That's what I was thinking, but it was hard to tell what people did in photos I have looked at.
I'm sure you will get different responses and different techniques. That's so great about CC is gathering on the wonderful knowledge, then applying it "your" way!
I always use a light brown colour fondant that way when you paint it with your alcohol and colour, you can get what ever depth of colour you like.
If you want it really dark you can also you chocolate fondant. I have attached two cakes for you, the garden is painted brown fondant, the tattoo cake - the board is chocolate fondant - no need to colour, just brush with alcohol once you have finished to give it some shine if you like.
Doing woodgrain finishes is one of my favourite thinks to do on cakes or boards - I have a few of them!
Best of luck,
Nice cakes! I appreciate the visuals! Thanks.
