I do my own in Microsoft word based on an A5 landscape and folded in half, at the moment I print these myself by looking at local printers I can have 1000 reproducted for about £25! Not bad, I work for a printers and we buy at £9.00 based on hundreds of thousands......The only question is on the design, do you feel confident enough to do your own or do you pay the printer? I do my own as I make tiny changes from time to time and this costs more if amends are done with a printer or designer.
