I also have found it very benefitial to strop in the evening. Many days I'm slightly rushed in the morning, and I found that concentrating on the strop was a difficult task while still thinking about getting out the door on time.

I began to strop in the evening, which allowed me complete concentration, and ample time to make sure I was completing each pass perfectly. After a couple of months, I was able to begin in the mornings again, but after a short time I realized that I thoroughly enjoyed my evening strop sessions and returned to them. As with advice from Noggs and Stubear, spine leading at all times, and train your fingers and wrist correctly the first time. I still don't go very quickly, but each stroke is done well.

Have fun,
Maxi
