I use regular copy paper - with the small stitches I never have a problem. However if you make a mistake - you might as well start over - it's not fun ripping out those itty bitty stitches. :x

I use Newsprint paper and also Vellum Paper(it can get pricey but it tears like a dream). I also use a size 14 needle with small stitches, that is what I was told when first learned how to PP.

I tried this method and had absolute "AWFUL" luck. The paper shrunk when I ironed the pieces. I use Carol Doak PPing paper. I buy it at the LQS or order it when I have a chance to add it to an order without adding to the shipping charges.

I'm going to a retreat in a couple weeks where the instructor for the class will be teaching us to use a "no-rip" method of paper piecing. I'm anxious to find out how to do this as I absolutely "hate" taking the paper out after sewing. If I can actually figure out how to do it, will try to post how its done.

I was using regular printer paper already in the printer. For some reason, I thought I'd get better results using Carol Doak's paper. Well, I had trouble right away because I could only get it to feed through the computer one sheet at a time (not insurmountable). But then I didn't think I liked it any better than my regular computer paper. In fact, I don't like the way her paper curls up and makes it difficult to work with. I'll stick with regular computer paper in the future.

I can see that we just created a paper shortage at Dollar Tree! I better get mine before the word gets out too far! :D

I just use ordinary printer paper. Ever since I started using the method where you fold over your paper piecing pattern before you sew and thus do not sew through the paper, what kind of paper I use has not been an issue. And it makes the paper piecing so much more fun!

I use unprinted news print paper which I get free from my local newspaper (end of rolls they cannot use). I draw the pattern on one piece, then staple several pieces together with the drawn pattern on top and sew over the pattern with no thread in the machine. The paper tears off easily.

My best advice, after choosing your paper, is to use the same copy machine for all copies. Learned this the hard way. If you switch copiers, the pattern may not be exactly the same. Then it gets tricky trying to make the blocks match. :)

i have some of doak's paper, cheap beige doodle pads in the kids dept., and then i got to sam's-get their sandwich wraps papers, unwaxed. then the other paper i use, i get from my drs office, i do pay for a roll of his exam table paper............cheaper and large roll.
