I have also thought about the kind of fun Halloween shirt I'd like to wear for Halloween. I don't usually dress up but I do like to wear a Halloween themed shirt. I pictured in my mind exactly what it should look like, and then I started doing an internet search for it.
I was thinking of something pretty close to this:
(Which can be found here.) This cool shirt was done with bleach art!!
Of course I googled bleach art to find out more about it. I loved all the different pictures on this site. Lots of great ideas!
I had also recently heard about using freezer paper to make a stencil, and then painting a shirt with fabric paint. (Freezer paper will adhere to fabric when it is ironed, just cut it into your desired shapes, iron, and paint with fabric paint--it will peel right off when you're done.)
I think I will try to make a shirt similar to this one with freezer paper and bleach. Stay tuned for the results. (It may take a few days, I'm pretty busy with necklace orders right now and my house is a mess too.)
