Hey shtick! I wouldn't recommend it. At least not without some adjustments.
The fleece patterns were designed to take advantage of the fleece's ability to stretch. Most fur doesn't have a stretch to it. They do make a furry fleece these days that does have some stretch to it and I believe some of our customers have used it with the fleece patterns and it appears (at least from the pictures) to have worked just fine.
You probably could scale the patterns to use non-stretch fur. My guess, maybe 90% of the original foam head
OR scale the fleece pattern up 110%. Only a guess, you may have to work with that a bit.
Another thing to consider is the direction of the nap of the fur. The fleece patterns are the typical two piece mirrored style of patterning. You may have to splice them up to get the direction of the fur going where you want it in the places you want it.
Of course, you can always make a custom fur pattern! Swazzle's tutorial -
http://swazzle.com/blogs/2005/12/bark-production-journal-fabrication_20.html - should prove helpful in that department. Use a non-stretch fabric, like a broadcloth, to pattern your pieces. Pin and cut just like Sean shows in the tutorial, only don't sew them together. Take them off, trace them, and presto!...you've got a fur pattern.
Hope that helps!
