Just a slit, a slit in the wood of our sideboards gives a hint that there may be something else there--in that thin little cranny. They "appear" to have long, deep drawers--and indeed they do. But they also have a hidden compartment, hard to see--cleverly covered by garland flourishes.
Another one of those great hiding places for special things. In this case, scissors, masking tape, signs and booklets that you'd want easy access to in a family room! Check the crannies--they are probably there.
