Well, i think i may have found something that will work for what i want to do... Pellon 910 Sew-in Featherweight interfacing. It was available on a 10 yard bolt (20” wide). I ordered it online yesterday and it should be here by the end of the week. All i could find locally were the fusibles, but i really didnt want that for the string quilt foundations. I will experiment with a block or two and report back! 😊
