Forget your City of Truro, or that DCC controller, how much do we spend on all the stuff that we never see on the layout?

I ran out of blades again this weekend whilst attempting yet another go at the shops for the market square on my layout. I couldn't make it out to get some proper blades but did pick up a cheap craft knife which has one of those blades that you snap off the end of the blade and use the next bit as the point with the theory that its sharp, because surely a blade is a blade. WRONG!!!!!

Ok it cuts card OK but it cannot do fine work even with lots of light scoring, and this got me thinking. How much have I spent on all the Odds and Sods over the years used to make the kits, so I a quick look round the shed came up with

2 decent craft knives (I lost one, bought another and then found the missing one a day later)

Lord knows how many packs of blades I have bought and I need another.

Cheap craft knife this weekend.

OHP to print windows on

Various types of glue - PVA, Super glue, UHU, Scotch mounting glue.......

Metpack glue. (Gone through loads of this as I have knocked a couple of full bottles over whilst working)

A pair of tweasers which I barely use.

A glue thinner which has never been used.

So with all the fun we have debating pricing policies of stock, I'm going to try and keep track of what I spend on Odds N Sods whilst building Alevscot, and see what I come up with outside of the ??100 budget I have for the its construction.
