I see no point in making something yourself if it's going to cost more (and likely not look as good) as one you can buy.
I'm all for a bit of DIY, but only when it makes sense!
I don't agree with this. I think it's important to make my child's cake and not pointless even if it does cost more..... Plus, you're probably going to spend more by buying a big enough cake for 20+ kids x
I was referring to the decoration, not the entire cake.
