neatly

Hi all, Usually when you re-glue or remove tensor rubbers they shrink. I was wondering how could I cut my rubber a little bigger than the blade's face and still keep it looking neat. Also, do scissors (those Revolution 3 ones for example) work better in general or those rubber cutting knives?

My tip is: 1)get the outline of the blade face size. 2)add an extra 1-2 mm for shrinkage allowance. 3)Cut it out. 4)apply the glue to both rubber and blade 5)Allow glue to dry,then stick it together.
