The idea of freezer or butcher paper is that one side can be ironed onto fabric, lifted and reused with out muss or fuss. So it can be used for many things, pattern paper for applique, stenciling, and many other things. I use it for stenciling patterns on canvas bags with fabric paint. It works a treat. Try this for hand applique, iron design piece cut minus the fabric turn over allowance, cut out piece with the sewing turn over allowance. with a hot iron press turn over allowance to the paper side. remove paper. You will have a sharp crease already folded into the piece ready for stitching down. It makes needle turn so much easier.
If you can't find freezer paper, look for a butcher who still wraps meat by hand and ask him to share his stash.

Looks like $9.99 is a reasonable price. A couple of us were going to send some, but that would be cheaper. Safeway doesn't have it there, huh? So great for doing paper piecing where you sew beside a fold and not thru the paper. Really is a treat! This one was done that way.

Reynolds Freezer paper is sold in quilting shops here in WA but can be bought online from Punchwithjudy.com if you're too far from shops

I buy mine from eBay. You can get Reynolds Freezer paper by the roll and it's much cheaper than buying it at your local quilt shop. Don't bother with Coles or Woolies; you wont find it there.

I got mine in a hardware store. Or a meat market that cut's meat for hunters or just a regular meat market. Also go on Google and ask.

Good Luck

Most of the specialty quilt shops are starting to stock the stuff these days. However, it is like most stuff here - not as cheap as I would like. We don't have a Spotlight or Lindcraft in our area, but maybe you could try them first.
I do know, that if you work in a school or an office, you could use the paper that photo - copy paper is wrapped in (i.e. the outside cover) It works in the same way as the freezer paper. That is what I used for many years, as there is a plastic sort of side to the inside of the wrapper. Try it on scrap material first, to make sure it works for you.

In Australia, these places use what is called newsprint paper. It is the unprinted newspaper quality paper that is often used for jotters or scrapbooks, so is an entirely different product. We don't have the same freezer paper in the supermarkets, but there are two sewing and home furnishing chains called Spotlight and Lindcraft that supply these sorts of things.

I get my freezer paper at our local grocery store. I bought a 75 sq. ft. roll. It's Reynolds Freezer paper. The size is 16-2/3 yds. x 18 in. The address on the box is: Reynolds Wrap Kitchens, P.O. Box 85583, Richmond, VA 23285-5583. Phone number: (804) 281-4630 It even tells how to use it for Quilting Applique on the inside flap.

This appears to be a good price on the surface, however, once the postage and handling are added on from Melbourne to Queensland, it looks like it would end up costing about $20 by snail mail and another $5.00 extra for express...I think I will stick to the photocopy wrapper until Cosco comes to NSW...

I bought mine at the grocery store in the department with the wax paper and plastic bags.
