A simple way to carry your branding to your packaging is to start with basic jewelry boxes, I like kraft ones, but black or white paper ones are nice too.

Roll on a little washi tape in a coordinating color around the box.

And tie up with a little bakers twine in the same color family.

Washi tape and twine come in just about every color. It's a fun and simple way to dress up a gift box and carry your colors throughout your packaging.
