I was in the craft shop a few days back looking at the "faux fox" material and realized two things.

1. It is a dead ringer for the real thing, especially at a distance, especially with a few tassles in the front, and most especially since it is worn where no one will be staring closely at it.

2. The backing on this faux fur is very supple. It would be easy to cut out a piece of this that is exactly the same size as the front of my black "semi-formal" sporran and stick it on with two-sided tape. That way I'd have a "convertible" sporran. The tape shouldn't harm the leather if not left on for weeks at a time or left in the hot sun. A bit of velcro around the edges may be usable as well. Still pondering this particular detail.
