Here is what you need:
- 3 sheets (letter sized; 8.5 inches x 11inches) of magnetic foil, in the USA Michael's sell them.
- 3 sheets of arts and crafts foam in different colors (cut to letter sized; 8.5 inches x 11 inches), in the USA Michael's sell them
- Exacto Knife or Utility Knife with new blade
- Paper Glue Stick
- Metal Ruler
- Printer, Computer
- 10 Push Pins
- Large Metal Surface (i.e. refrigerator, metal whiteboard, car)
Step 1: Glue Foam Sheets to Magnetic Sheets
Step 2: Cut Away Any Overhanging Foam Sheet
Step 3: Pattern
Alternatively you can make your own patterns. I.e. squares, diamonds based on 15 degree increments, pentagons, etc.
Step 4: Transfer Pattern
Use another pin to make holes in every pattern intersection. This methods allows you to transfer the pattern without marking the foam and also helps with the cutting of each piece.
When you are done, remove the pattern sheet.
Step 5: Cut Out the Pieces
Make the intersecting cuts. Be certain to use a new, sharp knife blade and to hold the foam down with the ruler where you cut so that the knife does not rip through the foam.
Step 6: Break Out Pieces and Repeat for Other Sheets/patterns
Repeat for the two remaining sheets.
Step 7: Mosaics!
