. You can use anything for a foundation just keep in mind the weight after sewing. A few of my earlier string pieced quilts are very heavy because I used muslin. I have sewn on used dryer sheets, they all are very thin poly and have the same flash point as poly interfacing if that worries you. Over the years I have given up the make do way of thinking and buy the best for me products. I use the Gypsy Quilter Scrap tape in the 13" wide strips for string piecing. It washes away.
