Thanks for all the good advice. The tissue I picked up is from Peck Polymers and is labeled as Japanese Tissue (though that might not mean much at the end of the day), so I must assume that's indeed what it is...And this is not the first time I've 'lost' a plane to her. She has also apropriated my Herr Cub. She's not sure she wants to learn to fly them (that's me talking her into it), but she's enthused about building them after seeing the progress of a Ben Buckle Quaker Flash that MikeSell's son (a real craftsman, that young man) is building for me.
