Best way to siffen and shap a panama hat brim

[silverfoxcc]

My hat is getting a bit floopy on the brim and looks more like the ones Barry McKennzie wears

Anyone managed to get a shapw baxck so that it stays ok?

One of the You tube videos mentioned spray starch, is this one of the con videos or the real thing?

TIA
