Privies & Prims

I have another wall hanging project ready for hand stitching on my camping trip.
For sake of conversation, when you do wool applique---
Do you do blanket stitch, or whip stitch?
Do you use all one color, or match color to the wool pieces?
My plan is to whip stitch, using only tan cotton, but I may change my mind.
