I've used cheap copy paper and newspaper with good results, but the ink does rub off of the newspaper. Recently I made a string quilt using the sandwich wrap paper. I went to Sam's Club and bought a box of 1000 sheets for about $7.00. It's tissue-like paper that some places wrap hamburgers in. The sheets are 12 inches square. My quilt was a string quilt, so didn't have any lines to draw. It worked very well. I just started across the middle diagonally, then added strips to both sides till the sheet was covered. Then I trimmed my blocks at 10.5 inches. Since it's tissue type paper, it tears off very well.
I also went to my local newspaper office and got some end-rolls of newsprint paper for my next project. They actually gave me the rolls free. I think each roll probably has at least 15-20 yards of paper and they're about 24 inches wide. I plan to use a paper cutter to get 8.5 x 11" pieces so I can run them through my printer. I hope that works.
