As we want to do a general club calendar as well how about making it double sided so that one way round it has all the DD related bits and on t'other side general club bits ?
Not trying to chuck a spanner in the works just an idea maybe worth considering ?
Saves doubling the calendar effort, potential to run a better quantity to keep cost down (realise it will cost a little more double sided) More club info in one place if we decide to sell them more widely ?
