I finally have some time to upload pics of my eReader cover. I took a small Oberon Journal and "adapted" a la industrial velco. Following another DIY'er's suggestion, I first covered the back of the PRS-650 with black electrical tape and then adhered the velcro to the tape in the event I should ever have any regrets...
The small journal is a perfect fit for the PRS-650. And I have not seen any issues -- the device is very securely attached. The only thing that bothered me initially was that it involved me attaching Velcro to the beautiful leather case...but I overcame that once I saw some pics for certain Oberon covers specifically designed for the Kindle -- that also used industrial velcro.
Many thanks to MR'ers for the great tips and recommendations for this solution!.
