It is very important to create interest by mixing
textures together. It is imperative if you have a room with little
variety in terms of colour or pattern.
It is the combination of textures that makes
the difference. A mirror, and the glass and metal of pictures
can add shine to an otherwise matt surface.
Soft textured cushions can enhance the stark feel of
leather and so on.
Remember it's trial and error with bits and pieces to get the
right look . It can be fun. You can move things about from room
to room. Experiment with your own bits and pieces before
you actually buy.
A very rough rule of thumb. The more rough the more rustic,
the more smooth the more modern.
There are the practicalities of texture too, like towels are
better soft and fluffy while tiles are hard and shiny. Floors can be
soft and fluffy or hard and shiny but should never be slippery. You
know- that kind of thing
