Here is a simple way to make this modern and minimalistic design using just tiles, tissue paper and a laser printer.
It is time to amaze your friends...
Step 1: Getting started
1. Nice photo
3. Nine pieces of 10x10cm tiles
4. Five sheets of printer paper
5. Five strips of 10x20cm tissue paper
6. Double sided adhesive
8. Exacto knife
9. Decoupage glue
Step 2: Picking and editing you photo
Chose which part of the photo you want to use and cut out a square. Put the square in a new document.
On this new document you can:
Change image size to 30cmx30cm.
Desaturate the image.
Change brightness and contrast until you get the desired result.
You might want use the paintbrush to get rid of unwanted details in the background.
You might want to reverse the picture, otherwise you will end up (like me) with a mirror image of your original photo.
Step 3: Dividing your picture into smaller elements
Make lines on your edited photo at 10 and 20 cm. This is just to make the next step easier, if you find it hard you can skip this.
Cut out the squares between the lines. Cut 0,5 cm away from the lines! Otherwise you will end up with a distorted face in the end. If you did not make the lines just check the ruler and make the cutting free hand. Each square will measure 9cm in each direction.
Paste the squares into 5 new documents, 2 in each except for the last one which will have just one square.
If needed, rotate the new documents to make them printable.
