Sedative said dried insects
Butterflies, beetles, mantids, etc.
Insect collecting duh!
You get a net. Catch a butterfly. Put it inside a jar with some sort of DEADLY fumes in it and KILL the poor creature. Take it out, put it on a mount so it will be ina desired viewing position, then lay it out in the sun to dry, careful not to let ants find it. I have horribly negative karma already from all the insects I've placed in the 'gas chamber'.
Oh and I also collect weird small stuff. Strange rocks, feathers, fern leaves, etc... then stitch and glue them together to make voodoo mobiles.
I have *counts* 8 hanging in my room ceiling right now. First time I made one, mom asked if I was turning satanic.
