NOT a good idea!

I thought I would save a bit of tree, and avoid the need to fill my shelves with huge files, by printing the second draft of my novel on two sides of the paper. After all, I was the only one going to read it. I like to do an in-depth edit on paper. Yes, I know it's stone-age but so am I. The trouble is that, if I decide to delete a chunk or add a paragraph or two, I have to re-print a page.
And that's where the problems start. I have to print two and a half pages just to replace one, then the pages don't match, so when I return to the computer I get lost and can't find which page to change, let alone which words. I can't do it all on screen because of poor eyesight anyway, and I write differently if I'm working directly onto a computer.
 Dammit - I can't even blog about it without getting muddled!
So from now on it's single-sided, double-spaced, and a big, fat lever-arch file, and the hell with it!
