Just a random thought, do you have the space to accept all the clothes and sell the stuff you don't want or can't fit, like on ebay?
We don't really have the space to accept everything - I will put it in the loungeroom, go through it and that which we don't need will go straight in the car... I know I could sell it on ebay but I feel a bit guilty profiting financially on something we got for free, you know?! I know I shouldn't - the people who give them to us would never know, and man, we could certainly put the extra cash to good use, but... I don't know. Might have to learn to jump over that particular hurdle as well!!
