Might I suggest that you use corroplast rather than foam core.
Foam core is much more fragile than corroplast.
BTW using fleece, I found had more "stick" for your blocks, than flannelette.
Rather than going to an office supply store, you should be able to get a much better price via a sign shop. Full sheets are 4'x8' (and sometimes larger) or better still, ask to buy their offcuts, which sometimes are quite large and an even better price!
If you have access to a heavy stapler, it will staple easily through the fabric and corroplast. And too boot, at a much lower cost, than miles of duct tape!
Good Luck!
