"Lovely little set but not 13 x 18cm!" star star star star star_border These measure 9 x 11cm and I would not have bought had I known this. However these are really nice and I'm so glad I've got them now! All you need is the white cutter with a red template clicked on top. Cut your shape then flip over to impress your chosen design (I used the solid white shape to cover the cutting edge for comfort but I think it is really intended just for storage).
