I've just put a pic of DS's birthday cake which was a spiderman cake on my profile. I'm a novice but found a great tutorial on youtube. I covered the cake in white fondant and ising a cocktail stick marked out the eyes and than the web lines. Next I painted the red bits with gel fondant colouring (from Asda) mixed with a little vodka. When that was dry I dipped the cocktail stick in black gel fondant (neat) & painted on the lines. This was really easy as I just followed the indentations and the cocktail stick was easy to control as it was rigid. I should imagine this would work for cupcakes too. HTH
Yes, that looks like - cakes covered in red fondant - web pattern drawn on in edible pen (not gel icing pen) - eye shapes cut out of white fondant and attached to top of red fondant - draw round eye shapes with edible pen
Countbapula, its the ready roll sugarpaste/fondant, you can buy it in already coloured red in small 250grm packs in asda/tesco, if you just want it for cupcakes, if you want to cover a whole cake then its best to buy the bigger packs from a cake decoeating shop.They are around £1.50ish to buy.Let me know if you want any help and advice ok?
So you can keep the fondant nice and flat all you need is a smear of buttercream on the cake then that will act as a glue, the put your disc on top, you can buy edible glue its in a small pot to attach the other things.hope that helps?
