Doublesided Tape and a glue stick.

I'm sure you'll all already know this one, but once you've added your doublesided tape, run a glue stick over the top of the tape. 
This just gives you a little bit of movement before it sticks.  Also works with foam pads too.

Thank you Anna! I didn't know about that little trick, when I get back into full flow that will be very useful. Sylv
