NO SCALES!!!!!! no nono nonononono, baaaaaaad!! when you are into maintainance...yes.....but now? no!!!!! don't do it!!!
You'll probably get measured when you start anyway. Make sure to take a few piccies - one from the side and one from the front.
As other peeps have said...a blender of some sort, I don't like those little whisk thingies, they don't seem to work for me - lumpies everywhere. I have little tiny balloon whisks you can get from specialist cake makers shops (they use them for making icing usually in very small amounts).
Sweetners are a must!! tabulated only.
A good bottle......I use a 1 litre volvic, but I always break the top spots cap thingie so I needed to buy a little 500ml one so I could use the screw on top. You have no idea how many times my bottle has soaked everything in my bag (including my now poor dead ipod!!)
Several million bowls, cups and spoons since that is all you will be using!!
Some baking parchment or teflon paper for making fun things.
I'm also a chart geek, so I have stickers and things.
Ketostix - yes you wee on them, but your CDC will have some you can get. You can sometimes have a fight on your hands in the shops trying to get them.
Bad tape measure!! it did that to my brother and my dad too. Dad is ademant he is a 32......but the tape measure says 37. I think mens jeans just lie!
Have fun!!
