We LOVE when people share the dontbeadoormat love, so if you'd like to send a note to the lucky recipient so they know what awesome person has sent it , or if you want to keep them guessing with a mysterious anonymous message you totally can, it's up to you!
When you add the dontbeadoormat to your cart a "Your Cart" box will appear on the right hand side of the website with your cart items and a blank box that is labelled "special instructions to seller". Just pop what you'd like to say in there and it will be hand written and packed with their dontbeadoormat. 
Too easy mate.
