Good idea, just hope I don't need to do it MGM 
 
Jaykay - to work out how much length you need, do you do a tension square as for checking needle size, then measure how much yarn length you have used for a given area?   I don't have those tiny balances to weigh small amounts accurately, so would I have to count turns on the niddy noddy for every skein?

I count turns on the niddy-noddy to see how much yarn I've got.

I do sums ( well, I've done an excel spreadsheet) to work out how much I'll need.

If I can work out how to attach it here........

Oh my goodness, I thought I was finished with excel spreadsheets when I left work
