6/ With flowers
Real or fake, the important thing is that you add a little colour! The trick is to use a floral hair clip to attach everything to the brim.
7/ With a scarf
Just knot your favourite scarf around your hat to update the style. For example, a printed or coloured silk scarf will work wonders on a dark coloured felt hat. A mix of winter and summer style!
8/ With a little chain or some pretty rope
Wrap your hat in a delicate chain or some pretty rope.
9/ By making a large bow
Wrap your hat in a little ribbon or material (or even a scarf) and finish by tying it in a large bow. Simple, effective, and without having to do any sewing!
10/ With a patch
Thermo-adhesive patches can completely transform a hat, and are attached with nothing more than the rub of an iron. Another great alternative to sewing!
