Hi Samuel!
Oh Yes, It makes perfect sense!
Been there, done that....
The decal glue is not only on the back side of the decal, but also on the paper itself!
Cut out and soak as usual, and when the decal comes loose, simply pick It up (carefully), turn the decal around and let it touch the paper again.
You should now have enough glue on the correct side of the decal for it to stick.
Otherwise, a drop of future will work as glue (as already mentioned).
Cheers!
