Context: Well the PJs stayed on for a good chunk of this weekend - Splitcoast Stampers had a Virtual Stamping Weekend , which set a challenge every hour , over 18 hours . Given the time difference between the US and Australia , I got a sleep in on Saturday , starting at 7 am . But Sunday was the kicker , starting at 4 am .
