Making silicone wasabi

I've been working on the Wasabi project and wanted to show part of the process in making the Wasabi packaging.

First you get laminating sheets, white silicone caulk, and choice of food coloring.  Mix the desired amount of silicone with the food coloring until color is met.  Spoon out the silicone onto the laminating sheet that has been cut down to the needed size.  Lay the top over the silicone making a bubble.  Don't press or let it get flat, this will cause the silicone substance to ooze out.   Work the bubbles to the middle and the iron together with a medium-high setting.  Any existing bubbles should be moved with iron to the center or outer edge.  Cut to size and watch for any ripples.   The ripples can cause oozing.
