First off...The comforter. I found a variegated grey striped comforter, bed in a bag deal at Walmart. $49 for a king size. The back of the comforter was dark grey, but not so dark as to not work for my project.
2nd, I found an imperial symbol online and printed it to be 40 pages enormous, gather up my faithful assistant Gwennie (as pictured), and took to cutting out my 4 foot round Imperial symbol.
Also, not pictured, is the stencil for the "property of" written and xactoed out in Star Wars heiroglyphics which you will see situated in a later pic on the comforter when I go to spray.
All in all the longest amount of time spent was on cutting out the huge stencil for the main image. The rest was cake.
A few things I would recommend tho. One is to use cardboard at least as thick as a cereal box for your smaller stencils. Otherwise they will curl up on you after your first spray. I made some Imperial geek chubby girl undies and discovered one thin printer paper sheet is simply not enough!! lol
I would also recommend experimenting with your spraying technique. I started with the back of one of the shams to be used to get a feel for how it sprayed and how heavy a spray I would need to get it to show on the dark fabric.
And lastly, get someone to help you. As simple as this project is, you don't want something as silly as a slight breeze to mess things up for you. Fortunately my Mom is quite an amazing assistant, despite whatever strange new project I come up with, she's always there to help.
Thanks for reading!! And happy crafting!!
