How to measure snow

It snowed here last Tuesday, I was quite impressed, after all, it has been a while since I've seen snow. The snow didn't last, it tried again on the Thursday but again the snow was gone the next day.

Some time early on Wednesday morning I had to venture downstairs to find a clean nappy for Baby C, I looked out of the window and noticed it had been snowing. Alot.
On waking up at a more reasonable time I told Mr. C it had been snowing, he asked;

"How much?"
I told him; "Two pillows worth."

Which describes exactly how deep the snow was. If you want to know how deep that is, just put one pillow ontop of another and you will know.
Yesterday it continued to snow and now we have four pillows worth of snow.
