I cut the squares with a Nestie and added smaller squares of DP which I had overprinted with a crackle stamp. Although it doesn't look like it, there are three different colour papers on this card, but the subtleness of shade and the overprinting makes it all look rather similar.
The stamp is a gorgeous one from Magenta and I printed the sentiment on the computer as I didn't have a stamp in a suitable size or font.
I quite like monochrome cards.
P.S. My name & blog address are just on the piccie... not on the card... I discovered that I could change the angle of the caption when doing this, that's what probably caused the confusion Annie!
