Hey Ria!
Not sure if this is helpful at all... but have you considered instead of doing the ribbons, with the wall, etc... doing the larger hard plastic badges and using custom login to "print" the ribbons on the badges? We have been looking into this for another event we are doing and are doing it digitally to print on the badges so that it doesn't take up so much space. You can also make it completely custom so, if its a speaker the background of the badge could be a totally different color, etc.
