After scribbling info on many pieces of paper on dog walks to passing strangers then we got business cards last year. Image and url to THS logo artwork in weblink below.
We are not aware of any template. And such a request may be complicated due to varying dimensions of business cards.
In case useful, we chose to use the mini business cards from moo.com. The small size (perhaps half size standard business) has worked well for our travel lifestyle.
We’ve given out many cards. To be honest, we have not observed some form of flurry of THS referrals. We did ponder adding QR code to design and re-printing cards, but deferred that until use up current batch of cards.
Happy referral hunting
