For this Drawing, I decided to do an old-fashioned (?) physical drawing, rather than using a random number generator.
Using my Drawing spreadsheet, I printed out a list of the names associated with each of the eleven (11) entries. Then I cut each name out separately, folded them twice and put them into a small container.
At this point, I enlisted my wife. I held the container of names above our heads and asked her to draw out two names, one at a time. I noted the order of drawing on each entry, and proceeded to notify each of the winners from there.
