Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.
I think it would be pretty easy to make.
Sugar cookies cut into thick dough with a bent paper clip hook baked into it can work. I'm not a food chemist, but I'm sure that my changing the recipe a bit you can get something that is very hard. Frosting and/or spray paint can be used to get the color you want (or food dye in the mixture), and then some spray on glue and glitter can make them look really nice.
Have you contacted your local Girl Scout Council? Tell them the age of children you are using as your labor pool, they might be able to suggest some ideas that different scout troops use in their district.
(Boy scouts tend not to do things like this.) :(
I don't know what trees grow in your area, but Liquid Amber trees have a really cool spiked seed pod that is about the size of a large cherry, and it is all spiky! They can be spray painted different colors, and then thread can be tied around them to form a loop-hook to be used to attach them to the Christmas tree.
Sounds like fun! Do let us know what you end up doing!
