I am making hampers for some of my family members this year... I have all my ingredients but am not sure if it is too early to start.

Most of the recipes say that if stored in an airtight container then they should be right for a week... some say two weeks... my question is do I really have to do this during the week or could I possibly start of some of the longer storing things from tomorrow?

Are these storage times a guide? or will the food spoil and be completely wasted?

I am making:
* Shortbread
* Spiced Cookies
* White Choc Fudge
* Butter Biscuits
* Choc Bites
* Palmiers
* Truffles
* White Christmas Fudge
* Hundreds & Thousands Biscuits
* Evil BB Fudge
* Fudgy Buttons

If you haven't noticed this is my first attempt at this hamper making deal... I am fairly confident I can make the items but my usual baking gets eaten same day so I am not too familiar with the storing side of things.

Thanks in advance
