Sure I can share, can’t recommend as I haven’t tried them out yet.
There are 3 I’ve found which are also low price (I’m in the UK, no idea about prices elsewhere). I’ve ordered 2 of them to try. Info from the web:
ReCreate is a blended yarn that is 40% wool from recycled garments, 30% acrylic, also from garments that have been recycled and 30% polyester that comes from plastic bottles that are shredded and spun. The yarn lends itself to beautiful stitch definition with strong cabling, lace detail and texture stitches all featured in the designs.
