Whenever I get something with lots of plastic packaging, I save all flat bits for use in templates. I don't know the name of the plastic but here it is used in food packaging, toy packaging, lids of shirt boxes, etc.

My MIL used to use the butter bowl lids!
I still have some of her plastic butter bowl templates!
and I made my first several quilts with them.
I traced around them with a pencil or fine pt pen and then cut them out.

if they are straight lines, no curves, try your local glass cutting shop.
I've had dozens made of c.1/8" plastic.
I paid 50 cents each, $1 if large

I brought in what I wanted PRECISELY drawn on graph paper and told him they had to be absolutely accurate.
He was off only a couple of times.

I just make one block and then measure and cut all the pieces at once and just remember what size i am cutting everything. it works for me this way. I don't like trying to cut each and every individual piece one at a time. takes to long for me.

School glue either the stick or white washes right out , can peel the paper off :wink: I use it for paper piecing :thumbup:

I use tape when I have a paper piece

freezer paper makes great templates. can be ironed on over and over.

If you are interested I have templates I send out for free. I have a 1 1/2" 2" 2 1/2" 3 1/2" now. If there is any other size you would like just email me or pm me.

This works great for me. Find and old photo album, the kind that used to have plastic sheets that you lifted up, placed your photos, and then put the plastic sheet back down. I found one easily at a local thrift shop. The pages of those albums are just sticky enough to use for templates. They don't shift and they don't leave any sticky residue on your fabric.

I use freezer paper for English Paper Piecing and I have glued on copy paper templates to be rotary cut around for odd-shaped paper piecing. I have also used light weight cardstock--the little subscriber cards that fall out of magazines.
