Just Bento

I recently bought a few packets of stencils for sprinkling furikake to make trains, cats or rabbits. Stupidly, I read the instructions once then threw them out before actually using it. When I went to try it, the furikake didn't stay anywhere I wanted it too, and what was there came off when I took away the stencil. What's the trick?

Seeing how popular the What's Your Box thread is, and since I'm as curious about what other people use as bento boxes as anyone, I started a sister Flickr group for our existing Just Bento group: Just Bento: Bento Gear. This is a pool for posting pics of bento boxes, accessories and other gear, not bento contents. There's nothing there yet but I hope you'll all join and post your bento gear porn! ^_^
