Agree with the others, I try not to use a 'wet glue' unless absolutely necessary as it will warp card and paper.If I have to use a wet glue I will use something like UHU rather than PVA as I find that is the worst offender for warping. I use double sided tape, but that can be very unforgiving with positioning. I use a Pritt stick, a glue pen (Zig 2 way glue) or my favourite is Stix 2 which is glue on a roller not refillable though and at �1.99 a time can get a bit expensive.
