Having almost finished re-basing and repairing my Confederates I have moved to the Yanks. I have used the same basing technique (with flowers) although progress with the sieve seems slower/harder.
These boys have the original flock scrapped back. I have repaired damage areas by covering with sand, This I will paint and dry brush before applying the new flock and flowers...
Examples of the finished item - although I still have to touch the paint jobs up and re-varnish.
