A blank not made out of clark foam, but out of cardboard. Is that possible? Yes it is! Mike Sheldrake has done some awesome work and found out that cardboard is a great alternative for that old and environmental unfriendly method.

And yes, the constructions he developed, are as strong as Balboa. And the nicest part: the blanks are are turn key, so no extra sanding and shaping is needed! Once the cardboard puzzle is in place, you can glass it directly.
