I've had this problem a few times. Once I put my cookies sticks in the foam they twist around (and face backward or sideways). Does that make sense? I'm wondering if there's a way to keep them from twisting & turning once I put them in the foam?

Dandelion, I have the same problem, and didn't think of a solution until I read your post....How about we try dab of hot glue when we put them in, hold for several seconds. It's the weight of the cookie that makes it turn, I think.
Also I have found if I use that hard green styrophoam stuff, doesn't work so well. I use this green rectangle blocks called desert foam (I think) that come in packs of three, it's next by the artificial flowers at walmart, that works best for me.

i just place a dab of royal icing in the hole or melted chocolate which ever i have available. Or if i have nothing available, i place a bit of the paper shred in the hole with the stick.

You also will minimize this problem if you don't move the sticks around once placed in the foam.
