ADVICE..... careful in washing the ties. What a mess! I have 3 large bags of silk and poly ties that I intended to use in making a scrappy quilt. They smelled musty so I washed them. Oh what a tangled mess we weave .... And some frayed horribly.
I then started dismantling them and ironing them. I do intend on still using them for a scrappy quilt, but I really recommend stitching them to muslin first (or to a fusible interfacing), then piecing them, then washing them.
The tangled mess wasn't so bad, kind of like a puzzle. But the fraying was concerning.
