Careful with the blue foam you can buy cheap from builders merchants.......this is often a very 'rubbery' foam that when sanded drags big lumps out (OK for hot wire cutting wings though)
If you want a nice closed cell sandable foam for making plugs etc....'IB Styrofoam' from Sheffield Insulation. It works a bit like 'Oasis' used for flower arranging, but is MUCH lighter.
