I love freezer paper. It is useful for SO many things in quilting!
Here is another great use for freezer paper, even those little scraps you might toss in the trash.
Write notes to yourself (or others) and press the note to a fabric instead of tape, sticky office dots, staples, or pins, which may damage fabric, especially pins that might stick you someday!Even safety pins can rust and leave holes in the fabric.
"Save for binding on Mary's quilt."
"Save this piece of backing for sleeve."
"Has been washed."
"108-inch Wide Backing - washed and pressed"
"9.5 yards" - Cross through that amount when you cut off a piece, and write the new amount.
Numbers or letters that are keys to your pattern, a piecing order, or a quilt layout idea.
I have one fabric with a freezer paper note that says "This red fabric bleeds!"
How about this one: "Free to Good Home."
Save information from selvages when they are cut off. You might want to have that information later. Write it on freezer paper, and press it to a corner.
Maybe your guild has a sale or flea market. Roll a fabric piece, write the price or yardage on a strip of freezer paper. Wrap the freezer paper strip around the roll, and press the strip to itself at the end.
I bet you can think of other things you might want to note on your fabrics ...
