Mounting unframed tyvek print-large panoramic

[Kathy]

I have a 7' x 20' print on tyvek I am having trouble mounting to a wall for exhibition. We are trying double sided tape, dowls, wood slats. If anyone has experience mounting panoramic shaped work please reply asap, it's going up this week! Thanks.
