Hi Bj,
I made a queen size bed quilt using freezer paper 'patis'. After ironing onto the fabric and cutting with the seam allowance, I was able to put them in a small bag and carry them with me everywhere. It bacame so easy to stitch around the paper that I could do it as a passenger in the car at night, just by feel!
Best of luck with your quilt. I hope you enjoy making yours as much as I enjoyed making (and now sleeping under) mine. Viv
