they seem rather big to me!!its more like a letter than a ticket!!each to there own though!

i just have business size cards with WINDOWS CLEANED TODAY in big letters on the front.
I CLEANED YOUR WINDOWS ON:DATE
WATER FED POLE AND TRADITIONAL WINDOW CLEANING
CONSERVATORY ROOF/FASCIA CLEANING PLEASE PHONE DARREN:PHONE NUMBER ON THE BACK
If they want to pay by BACS i have a seperate piece of paper with my bank details and instructions on.i only have to give them my bank details once then they have them stored on their computer.
I leave a SAE if they pay by cheque.
the cards are a handy size and fit nicely in my wallet so make it easy to post through customers letterboxes.
works well for me.
