I need some tips on a square cake covered in fondant. I always end up cutting strips out at the corners and trying to match them up then smooth them out. Is there an easy way so I don't have to trim? I can do circles okay, but not sure how to do the squares without all the extra. Thanks.

The trick is to start with the corners.

Lay the fondant over your cake and smooth the corners first using both your hands on either sides of the corner. It's then very easy to smooth the rest.
