Hi beauties!
I think that business cards are excellent! when i pack my cookies, besides printing my logo (i use it to show the logo AND to seal the package) i like to give it a more professional look by printing an extra card that shows the type of cookie they bought, the ingredients, the contact and a special thank! (i divided my cookies into 3 secctions: "Le Petit Cookies" (5 to 7 cms) "Le Grand Cookies" (10 to 12 cms) and "Le Bouquets" (flowers/plants cookies built into a bouquet). I came up with this idea because i think this helps the customers to remember what they bought, and let them choose between the 3 categories i offer!
I hope my idea can help you!
Ps; this is what it looks like!
