Hobby crafts are a lot of fun, though I must admit I'm a total newbie at them. My father has been model building since he was a child, and is quickly passing on the love of building things to me.
My father has a number of interesting hobbies, but the newest one is his 3D printer. He printed me out this Jiji cat from Kiki's Delivery Service, and three Totoros from My Neighbour Totoro! I think they're pretty cute. He's really gotten into printing little toys and other fun things.
My father and I built two foam plane from FliteTest. He downloaded the patterns for free and I traced them out. Then he painstakingly cut out the patterns for us to build. It took him quite a chunk of time. But, they came out pretty!
