Tomorrow marks the start of National Letter Writing Month (who knew that was a thing!?), so I'll be rounding up some of my favourite greeting cards this week. Who doesn't love to receive unsolicited snail mail? So pull up a chair, turn off your computer, put pen to paper and reach out to some of the people you love...the old fashioned way. Don't know what to write? With their cute sayings, the cards I've rounded up today will start you off in an easy way. (Don't forget your stamps!) Why Hello There, $25 US (set of 10), Kate Spade New York.      Estelle Hello Green Notes, $13 (set of 12), Indigo.   Watercolor Note Card, $18 US (set of 8), Rifle Paper Co.
