I finally got around to trying some of these out. Over on Inkjet_Paper_Scissors, Grendelsmother64 has put together some fantastic, easy to build boats. Pics will have to come later - it's getting late and my eyes are wearing out. But, I've built the canoe and one of the faering boats. Tomorrow I'll finish up the viking drakkar longship model.
They're all wonderful models, and there's lots more there, too!
