After many years of using spray mount, re-positional spray mount and pattern stuck down with transparent film I discovered A4 labels (thanks to toesy and Martin) and have never looked back.
I make up an A4 sheet of the shapes I want to cut then photocopy it on to an A4 label. I initially cut out the shapes and stuck them all on to the wood but had some problems removing the excess due to it being stuck on to the wood, sometimes for a few weeks. Martin's tip was to cut out a shape from the label, stick it on the wood, cut it out then remove the excess bits - all in the same cutting session. Works a treat.
No spraying or adhesive marking up with tape. Just cut out the shape from the label sheet, stick it on the wood, cut out the shape, remove excess label bits. Doddle.
