Did I buy my girls matching dresses that coordinate with my #bookcover for my #booklaunchparty ? Why yes. Yes I did.
And this brings me to another little author tip. Pick a dominant color from your cover and use it as a theme at events - signing pens, your outfit, the tablecloth you put out at signings (wait... you don't put out a tablecloth?!? Well there's another tip. Get a tablecloth on Amazon or at HomeGoods or something. Totally cute, like $7, and makes you stand out at the venue).
