Query: Magnets are too weak!

We bought a bunch of sets of M&D; magnetic animals, numbers and letters for our craft project. We made a quilt landscape and glued it to the metal sheet to make an 'animal park'. Imagine our disappointment when we realized that these magnets are too weak to hold the figurines through the thin fabric!All our craft work was for nothing, just because M&D; used very cheap magnets. Joy killers.They stick to the bare metal, but nothing else.
