Love a Morris chair, and there are miles of good plans out there, and resources to roll your own. I really like Bob Langs books, and he covers what needs to be covered very well, with pics

Something of a starter page to help direct you through Bob's books, and info.

Seems since I last looked he has added the plans as well. Stickley 369 slant arm. 

However you decide to go, I'm certain you will make 2 very nice chairs.
