Here's a quick cheat for adding a terazzo pattern to anything fabric. 

You will need

• Iron-on vinyl
• Scissors
• Iron
• Fabric item

Step One

Cut thin strips of your iron-on vinyl

Step 2

Cut little shapes from the strips. The key to the terazzo look is to change direction half way through each cut, giving jerky irregular-shaped pieces 

Step Three

Put your fabric item on an ironable surface first! Then lay the little pieces in a random pattern. Be sure to have the sticky side of the vinyl down,  you can usually tell from the finish which side is which. The very even side with no marks is usually the side that should be facing up. 

Step Four

Iron the shapes on. Press with the iron but don't move it about. Check the instructions for how long as different brands needs different timings. But do press hard, it helps the bond to form

Step Five

Peel off all the protective transparent layer on top of the shapes, and you're done!

You can use this hack on any fabric at all, I'm doing t-shirts next! Here's the not very full Pinterest board
