Sounds like everyone in the family uses the PRINTER part of your printer/scanner/fax - but you're the only one who uses the SCANNER part of it. So move it.
Or, check craigslist and garage sales for a used scanner - I'm not kidding, I think we had two in our garage sale last summer - you could have gotten them cheap- and I know the one that was mine was almost never used and practically new, had the book, software and cables with it, too.
You don't live in Illinois, do you? it may still be out in a box in the garage, waiting for a spring garage sale......
I collect patterns, too - Internet patterns are saved on my hard drive - but paper patterns..... well, that's a totally different story.
I do try to organize them - the free 1/2 sheet ones you get in the stores I have in a binder - but books and magazines - those are filed in a drawer - other than the ones I'm thinking about starting next. I'm just NOT an organized person, I guess! there is no way I would ever have the time to scan in my patterns and file them on computer!
Knitting is like sex, If I like you, it's free - if I don't, there ain't enough money in the world!
