Paint chips are awesome for crafting. They're thicker than card stock, they come in just the right colors you need, and they have a nice finish to them. Oh, and they're FREE! I made this for Mars' upcoming birthday, but you can make them for any occasion.
To make a personalized banner like this, you need
letters for tracing or stencils (optional, you can freehand the letters if you'd like)
First, trace and cut out the letters you need.
Next, arrange them together in order.
Then, use a needle and thread them together with embroidery floss.
Hang it up, and enjoy!
