One of my favourite baking site - CakeJournal, is offering its tutorials in PDF format. And you can have them for free if you follow the instructions here. I have used this site often, for making cute cake decorations from fondant and for most creative ways of decorating cupcakes and cakes.
I got the idea of my Valentine cake also from this site. So go check it out and get your free tutorials.
Happy Printing your free tutorials!!
