Hi Berryberry - -
This will be my 2nd Boom, so I'm hardly an expert by any stretch. I think your fabric choice is fine. I suggest that you ask each 'receiver' of that fabric to use a white (or ivory - hard to tell from the pic) as their additional fabric unless you're okay with people trying to match the red and green. (personally, I'd go with whatever the background color is). You're going to have a blast! I know I did the first time around and am looking forward to this one.
