My first card was done for Day 4: Plainly White:
The other cards - three in total - were done for Day 5: One Stamp, Three Ways:
For all three cards I've used Hero Arts Designer Woodgrain stamp block.
In this card I used the stamp to give the flower some texture. The flower is created from 8 punched hearts.
Here I've used the stamp to illustrate a field of grass.
And for the final card I used the stamp to create a background. The stamp is used twice - first horizontally and then vertically. Here I've used to different shades of green, first a light green and then a darker green.
