well hi there
the trick is not to sell any models - or cull em - first of all:
Have your tried a slight persuasion method to the better half - say - you know that job you want doing (the one you never got round too) or the blouse she really likes - say WELL BUY IT darling, as long as I can keep me models.
The other alternative is, we have to teach you how to become very secretive - so you can hide models around the house

I know cos I have 12 in the loft

really you know, we should have a Course run by Mayhem called 'How to be deceptive in hiding models and equipment and where is the best place to hide them'

I know in the past, I have myself sold models - but you know what I have regretted selling one or two of them - and have even sold one that I rebuilt

but it did go to a good home

aye
john
