We're having end of the month Rummage Sale @ the senior center where I do volunteer work, end of the last hour, everything 50% off. T-shirts can do as low as 50 cents!
Since your having a hard time trying to search for some, you can make some of the things your own!
you can take an ordinary black pen that can be opened and closed and that is clear just like this one..... http://googleimageresult230.tk/ And then just print some paper that says your boutiques name on it. And just open the top of the pen, put the paper inside where you can read the letters, and then close it up!
easy as pie! Just buy some white non-worded t-shirt from a local store (i get mine at dollar general) and then follow these steps..... http://www.youtube.com/watch?v=0H_utRjIGsc
now books are not easy to make (lol) so just find some magazines you can sell for less there, or even basic books that tells you about dance! http://www.amazon.com/Books-about-Dance/lm/GBHEXMHL14C0 If your lucky enough you can find some at garage sales for CHEAP!!
HOPE I HELPED!!!!! THANKS
