I bought a block of artists' newsprint at Office Depot a couple of weeks ago. It works just as well as the name brand quilter's paper and costs a lot less. I do have to trim it, but I don't care.
I usually order a package of the name brand quilter's paper every time I order from Connecting Threads, so it's less expensive that way, too.
I just found this last week on eBay:

It's a bleached newsprint - not bright white like copy paper, though. Soft and easy to tear.
I have to trim it with the paper cutter to fit in my printer, but I get 500 sheets for the same price as 100 sheets of the stuff that's made for quilters, so it's worth it.
I bought four reams, so that should hold me for a while. :)
Free shipping and I actually got this paper the day after I ordered it, which is amazing.
