It's more of an illness than a hobby for my friend and I, I think.
We have a another set of friends that we scrapbook with regularly and we have such a good time. I haven't gotten to do much of it this year, and I'm SO far behind. (Still working on my 2004 book.) In fairness though, since 2005, I've made about 10 smaller books as gifts for birthdays and a wedding and it's just so time-consuming. I really love it though!
My friend got me started in 1998. Back then, there wasn't much stuff and when you told people about it, they looked at you like you had just landed from Mars.
Now, the stuff is everywhere and everybody does it or at least knows someone who does.
