I tried this technique a couple months ago, after finding it on Splitcoaststampers.com in the demo challenges forum... titled "TLC49 - Be a Blockhead! :)". It's called color blocking... & it reminds me of a Piet Mondrian painting: There are directions on the challenge page, but I used a template I created in Word. I drew a big rectangle & sized it for a card front, & then began filling it up with smaller rectangles & squares until I liked it. I printed off a few copies, & then marked it up to show what colors I would use where... and then lay the print on top of the card stock & cut through it to get my shapes. I then stamped them before pasting them down.
