AI saw edible pine cones made of pumpkin seeds on facebook recently. I have a birch bark wedding cake this weekend I would like to use them on, but I can't find a tutorial anywhere. I am not the best piper, so royal icing is out. Any ideas would be appreciated.

Here's a starting point for you.  This is a tutorial made by @costumeczar.  It might be helpful.  Good luck.
