Hi Gabriel, Thank you for reaching out. Yes, if you mail us a custom emblem we can take a look at it to see if we can attach it for you. We always recommend maximum height of an emblem to be 2 1/2 inches to look proper on our sizing of head wear. Place your order on the website for the hat and in the comment section on checkout page put - HOLD ORDER FOR EMBLEM coming in. Make sure to put a daytime number for us to contact you in case we have any questions. Don't hesitate with any other questions or how we can assist you ~ BHC Fran
