There was a time I had marbles coming to my house 2-3 days a week.There were singles and groups I always had coming. My routine was get my sorting tray, my loupe and my light source.....and a cold beer. I would cut the bubble wrap off and put the marbles in the tray with out looking at them. Then I would settle in and grab one marble at a time without looking and put it on my other tray and then Bang ! Another marble fix is begins. What about you guys.Do have a routine ?
