    The staples probably will not fold between the metal and carton. Most likely they will just stop and stick out from the surface of the carton. Your best bet is probably the 3M Super 77 (or similar) adhesive.Super 77 is dry and tacky when it sprays onto a surface. We used a cotton fabric and didn’t have issues with it bleeding through the fabric. However, it's possible that a silky/sheer fabric may allow some of the "tackiness" to bleed through. I don’t think it would show spots; rather, the surface would feel a bit sticky to the touch. Undesirable nonetheless.One thought is to not spray the adhesive onto the front surface and apply the fabric; rather, just use it to attach the fabric to the back.

Undesirable nonetheless.One thought is to not spray the adhesive onto the front surface and apply the fabric; rather, just use it to attach the fabric to the back. For instance:(1) Buy fabric that is significantly larger than the sheet metal so you have several inches or more of overlap on the backside of the sheet.(2) Lay the fabric down on a flat surface.(3) Lay the sheet metal on top of the fabric.(4) Spray the adhesive on the back of the metal.(5) Fold back the fabric edges and apply to the tacky metal surface and apply pressure to lock the fabric in place.(6) Work around the edges in a similar fashion. Make sure to pull the fabric tight before applying to tacky surface so face is smooth. (You can reposition if needed since 3M stays tacky.)(7) Lay the backing on top of tacky surface and press to stick.(8) Mount into frame.(9) Eat a delicious sandwich to celebrate how awesome you are.Note: Using this technique, you'll want to round off the corners of your metal sheet so it doesn't cut through your fabric when pulling it tight.

    We never glued the metal to the backing since the frame + backing + acrylic face kept it in place and flat. However, if you want to glue it I’d consult This to That for the magical answer (I've never tried liquid nails). Metal to wood comes up with several options. You can choose other materials using their tool if desired.

    Fabric works nicely (we tried it). We used 3M Super 77 to make the fabric stick to the metal sheet to give a nice, uniform, flat surface. When applying the fabric to the metal with the adhesive:(1) Cut the fabric so it is much larger than the metal sheet. (2) Apply adhesive. (3) Start at a corner and slowly roll fabric onto the surface while smoothing out wrinkles along the way.(4) Trim the fabric about 1-2 inches from the edges of the metal sheet and stick it to the back of the metal sheet with more adhesive.
