Yellow parchment paper (which you can find at your local craft store)
Open your word processor and select a format for business cards.
Write the following text, taken from Harry Potter & the Philosopher's/Sorcerer's Stone:
Every Ollivander wand has a core of a powerful magical substance. We use unicorn hairs, phoenix tail feathers and the heartstrings of dragons. No two Ollivander wands are the same, just as no two unicorns, dragons or phoenixes are quite the same. You will never get such good results with another wizard's wand.
Print on parchment paper, cut out the labels and attach them to your wand parckages using a string.
