I've looked through all 3 pages of the felting discussion and didn't find any topic that covers my question precisely. Does anyone know just how much wool/with other fibers is necessary for the fibers to felt? For instance, 50/50 wool/acrylic = felting? I just bought this really old Bernat icelandic wool and orlon acrylic mix (50/50) rust colored yarn at my local thrift store. It has that "wooly" appearance to me. I paid a whopping $0.75 for 5 skeins of it. $0.30/skein x 1/2 price day = $0.75.
Are there any hard and fast rules for percentages of wool that will felt? For instance, is a 70/30 wool/acrylic blend likely to felt? What is the minimum percent of wool required for the fiber to felt? I did read that wool with 10% or more silk doesn't work.
You are never given a wish without the power to fulfill it.
i think it depends on how the fiber itself is processed. There is a Lion Brand yarn that is half wool that felts (Landscapes), it has an acryilic core and is wrapped in wool. The best thing to do, as Amanda says, is swatch. But the more wool the better.
I am bummed just now about some yarn from a thrift shop sweater. With labels that say 100% wool and dry clean only. I'm almost finished unraveling it and making balls out the yarn when it possessed me to knit a little swatch and run it through the washer. It's fuzzing up some and shrinking some but after several trips through the washer, in hot water, I can still count the stitches.
