A fly fisherman husband can be hard to shop for. When my wife got me the book "Tying Foam Flies" by Morris I'm pretty sure she was just trying to get me something she knew I didn't already have. I've never cast a foam fly, much less tied one. They seem a little ugly to me. Are foam flies *the new black*? The hot new thing? A passing fancy? Or a tool to whip out at the right opportunity?
