Dry Mount Board Hanging Conundrum

[RobM]

I'm framing this poster for the child's bedroom wall, and wanted to try using some foamcore to make a slight gap between image and the mount.

The aperture size is 835x585mm, but overall is 955x705mm with the mount.

Because it's a poster, I dry-mounted it, but made the mistake of cutting the mount board back to the poster/aperture size. If it'd planned better, I would have cut it to the overall size.

Ordinarily, this wouldn't be an issue if it was just a print that I cut suspend with tape from the underside of the mat/foamcore surround. But, because it's on a dry mount and is therefore relatively heavy, I'm concerned about securing this in what is a larger square area for the mount.

How would you get round this issue? I was thinking of doing something like that the attached photo, whereby foamcore is put together with an aperture that will effectively hold my picture/dry-mount in place. Would you do this?

Or...I've cut another piece of foamcore to the overall size and the temptation is to just stick the poster/dry-mount onto that, instead of forming more apertures. How about this tack?

Is this whole scheme too foamcore excessive??

Appreciate the above might sound hard to understand, so this photo might better show the layers involved.

Sink mount it with strips of board the same thickness as what it’s mounted to.

Then put whatever type of mount you like on it but it beats me why anyone would want to space a mount away from the image!

Okay, I'll sink it within another cut of the dry-mounting board. That will make sense for having a layer of adhesive to stick it all to.

You really don't like spacing away mounts, do you, John???

Well, this turned out to be a massive f**k up.

I started to cut another dry-mount board, but chose to retain the whole square area of it (instead of strips) and first stick the foam core spacer to it, followed my aperture-size image/dry-mount in the middle.

And herelies the frustration with dealing with adhesive boards...

The image wasn't perfectly centred, and of course can't be removed after the fact, and so when I placed the mount over it, it was uneven on the top side.

The reason I took this tack was, as you might see from the photos on the original post, I'd cut the original dry-mount board in a less-than-perfect manner, meaning that it would have still been sitting uneven within a straight-cut sink-mount.

What a waste of materials...

You don’t have to make a sink mount as such. you just have to make your mounting board flush, and all you need do is put the mounted print face down and tape too-wide strips around it. Then you can stick your mount to that and trim off the excess from the strips. No need to waste self adhesive board for the strips either.
