Okay ladies, yes, this is important enough for a new thread, I promise

The room that we are using as our nursery has low vaulted ceilings like in the photo below. (That is not our room, I stole the image from google.) I think that the cribs will come up as high as the vaulted portion or at least close to it.
I have my heart SET on using monogrammed wall hangings similar to those attached for the twins, but I can't figure out to how make it work with the vaulted ceilings, because there probably won't be room behind each crib.
Does that make sense? How can I put the monogram by the correct crib? Decals? Nail the monogram to the wall instead of hanging it? HELP this creatively challenged FTM!

Re: I need help from creative ladies!
Get smaller monograms
Paint on the wall or vaulted portion above the cribs
Nail above using decorative nails or glue jewels or stones to the nail heads after hanging
Go really high and hang them from the highest part of the ceiling by wire or ribbon.

Hell, I clearly can't decide, but I LOVE the idea.
Would I put the decal on the vaulted part? I would definitely want decal over stencil so that I could remove it easily. Wait....how easily to the decals come off?
I guess we could nail the wooden monogram to the crib so that they wouldn't be as much of a hazard?
I love all your ideas, ladies! Thank you so much!!!!!
