For me summer time means flowers and the brighter the better. I love all those reds, oranges and yellows contrasting beautifully with the greens. Here's an ATC I made for a swap over at Docrafts. I've used a pressed and dried flower and leaf so it will certainly be treasured forever.
I am going to enter it into Sir Stampalot July challenge - Lazy Hazy Days of Summer
also at Papertake Weekly - In the garden Challenge
and at Fun with ATCs - Flowers
Thanks for looking,
