So I'm ready early today - Sunday morning here in Australia, with temps in the 30s!
Stamp is a freebie from Cardmaking and Papercraft Issue 165 - love the fonts
Die is by Simon Says Stamp - Partial Cut Flowers
Button die is a set of 3 by Joy! Crafts
Washi - unknown origin but printed cloth tape about 1.5 inches wide
Below are a couple more cards I made using washi.
