Felt Your Sweater!: A Felted Wool Tutorial

sweater before feltingWherever you might normally stand on the felt controversy, I think that we can all get behind the claim that felted wool?

Is awesome.

Felted wool has all the benefits of wool for crafting–it’s sturdy, can be shaped, holds a dimensional structure well, is durable, and has an appealing texture–and has the eco-friendly attributes of being natural and second-hand. As part of my green crafting manifesto, I do not buy new things, nor do I intentionally buy products exploitative of the world’s creatures (please, don’t ask me about glue!), and yet when I buy a wool sweater from the Goodwill Outlet Store, I don’t have to worry about whether or not the wool has an organic certification, or about the high price of organic wool. I just think, “Yay, recycling!”

And yet, the wool sweater you take home from the thrift store requires some work before it becomes that versatile wool felt. Here’s exactly the work you need to do:

pieces I'm not going to felt1. For your wool sweater to felt evenly, you first must cut it apart at the seams (completely cutting away the seam–sometimes they can be thick) and cut off any ribbing or reinforced seams. You can still felt and use the ribbing, but it will felt differently from the rest of the sweater.

2. Set aside any parts of your sweater that you might want to incorporate into a project without felting–pockets, for instance, or buttoned cuffs. Also cut off any snaps and buttons to reuse in another project.

The best results come from heat (choose a hot setting), agitation (choose a setting appropriate for heavily soiled clothes), and a little detergent (if I’m felting a sweater that’s already slightly felted–perhaps it made its way to the Goodwill Outlet Store because its original owner accidentally washed it–I often skip adding extra detergent, but I do have a high-efficiency washer).

4. If your wool comes out of the washing machine felted to your satisfaction, you may line dry it. Otherwise, dry your wool in your dryer, on a warm or hot setting.

    This is such great information, I’ll be linking. Isn’t the thrift store the GREATEST craft shop ever?!?!

    I know! Estate sales and garage sales are also pretty tops on my list, too.

    I should have mentioned that when you throw your wet wool into the dryer to felt, you can also throw in a couple of tennis balls to add some extra agitation–that helps with the felting.

    I have been collecting sweaters to make into the backing of a baby quilt. I only bought 100% wool sweaters (from thrift stores) but none of them ever felted in the washer. It was only then that I realized that I have reversed water pipes and when I thought that I was washing them with hot water, it was freezing. I hate to think of all those “cold” water washes.
    As a side note, if you don’t have tennis balls, the cups that you use to measure liquid detergent work well in the dryer for agitation (nope, they won’t melt).

    No way! And how about all the times you thought you were saving money by washing everything on cold and the water was probably boiling!

    I accidentally partly felted a REALLY expensive organic wool mattress cover by putting it on the “air dry” setting in my dryer. It will likely take a couple of years of therapy before I can forgive myself for that one.

    Great information. I’ve been felting sweaters for blankets for several years, but I learn something from others all the time. Like, cutting up the sweaters BEFORE washing them – I will give that a try now.

    Also, when I have a lot of sweaters I take them to the laundry mat for the first wash – just be sure to wipe the washer out when you’re done since there may be some wool fiber left behind.

    Thanks again.

    Thank you for the very simple felting instructions. I am always on the look out for new and intersting ways to do things and this fits the bill. I am on my way to the thrift store!!!!

    This is a very helpful tutorial. May I add one suggestion? It’s very wise, when you’re felting wool in your washing machine, to put it into a fine mesh drawstring bag first.

    Wool items can throw off a lot of fuzz during the felting process, and these clumps of fiber can wreak havoc on many washing machines. A friend of mine had her machine conk out, and during the costly repairs, they found the culprit to be wads of fiber clogging the machine.

    A mesh bag is very inexpensive and keeps that excess fiber held in the bag. You can then pop the sweaters, etc. out of the bag before you run them through the dryer.

    Took a workshop on making a purse from felted wool over a plastic mesh form. The teacher had already felted the wool and made them into kits. It was so much fun I want to try it in another color and use an old leather handbag as the base. I didnt know about cutting the sweaters apart. They are so warm I’m keeping one to wear.

    How much does the sweater shrink?…how many sizes?…I have an angora sweater that my Mum knit for herself and it is really big on me…but dont want to shrink it to where it becomes too small
    Please advise
    Thanks

      It’s unlikely that you would be able to shrink the sweater in a way that leaves it perfectly formed, only smaller. The shrinking process is unpredictable unless you’ve shrunk that exact same yarn in that exact same sweater pattern before, and it’s generally very uneven–it may shrink far more in length than in width, giving you a short, wide sweater, the arms may shrink in width far more than length, giving you long but impossibly thin sleeves, etc.

    Does cashmere, angora qualify as wool? Would I be able to felt it? If I had a sweater that says 50 % wool, 50% angora, could it be felted?

    • http://www.craftknife.blogspot.com Julie Finn

      Most animal hairs, including cashmere and angora, do felt. However, the trick is that different hairs, and even different yarns made from the same hair, won’t felt the exact same way, so felting a blend of any kind can yield an unpredictable result.

  • Suzanne

    I have several sweaters that are 100% cashmere and they don’t look felted. I can still see the weave and am afraid to use them – how can I be sure? I’m a newbie.
