I am a scrapbooking fiend. I also like to make my own greeting cards. Having that hobby has saved my sanity more times than I count, lol. Surprisingly, it came in handy for homeschooling projects and activities as well.
The boys (ages 12 and 7) have enjoyed working on scrap pages for my books, so I decided this year we would try to let them do their own scrapbooks. They started off working with some of their favorite photos from this year, but then decided they wanted to scrap about things they learned about.
I discovered that there is actually a homeschool method similar to that, called lapbooking. The boys spend a certain amount of time learning about a place/person/concept/etc., then they create these little mini-scrapbooks (or lapbooks) with artwork, photos, and stories; just anything they want to include in them.
Outside of the fact that are choosing what they are learning, and really enjoying having that control, they are getting in extra arts and crafts time too, lol. And when they are working on their new hobby, I can have some time with my old hobby. :)
