Now that you have purchased your sweaters, you are ready to unravel! This will be my example sweater:
Since this sweater is obviously thicker than lace weight, the first thing I do is check the gauge. I keep this info so that I have a rough idea of what weight the yarn is, and have an idea of what patterns it might be suitable for.
It looks to be about 4 3/4 stitches to the inch to me. I'm going to call this worsted weight. This is a great chart that lists yarn weights and their average gauges.
Next we will remove the tag and turn the sweater inside out.
You'll notice that there's another tag on the side seam. Many sweaters have a tag there. It is good to know. If the label at the neck does not give fiber information, or washing information, you can usually find it here. We're going to use our seam ripper and take that one off too.
Next we'll begin deconstruction. MOST sweaters are knit in pieces, back, front, 2 sleeves. They are USUALLY seamed at the shoulders first, then around the neck, then the arms are sewn on, then the seam from wrist to waist is sewn. If we're going to take this apart easily, we want to take it apart in the opposite order that the manufacturer put it together.
That means we're going to start at the sleeve cuff and do the big long seam first.
MOST sweaters are also sewn together with a crochet seam. This makes taking them apart a piece of cake. A crochet seam looks like this: Notice how the crochet chain forms little arrows? Those arrows show you which way the seam will unravel. In this case, it is pointing away from the cuff and towards the armpit, just like I thought it would. I usually find the chain on the right hand side of the seam, but it can be on the left too. It can also be going in the opposite direction, so take the time to examine it and find out what it's doing.
At the cuff, the end of this chain is usually tucked back into the seam. Pull it out with the tip of your seam ripper and cut right smack through the middle of one of the links. Separate the seam a bit and pull the loose thread from the back of the seam. You can tug on this thread and it will unravel the chain from the wrist to the armpit and all the way down to the hem. It may get caught up a bit in some places, but take the time to gently get it going again. You may even need to snip another link in the chain with your seam ripper. If you don't want to cut the wrong thread, it is important to take your time to pay attention to what you're doing and work it out. If you do happen to cut the wrong thread, though, it's not the end of the world. On animal fibers, you can do a felted join and will probably never even notice you had a break.
I avoid using scissors if at all possible. It is possible to take a seam ripper or a pair of scissors and snip each and every seam thread without unzipping the chain. You do this by pulling the seam apart and carefully cutting the connecting threads. It is very easy, though, to pick the wrong thread and end up with lots of breaks in your new yarn. Sometimes it is necessary to do it this way, but most times not.
Occasionally I will see a sweater that has a good seam, but instead of a crochet chain, you will find what looks like a rope. Please excuse the photo. I usually find these seams on very fine gauge wool sweaters. Usually they are Merino, and usually they are men's. I LOVE Extra Fine Italian Merino, and love to get men's sweaters because they have so much yarn. I do not, however, love these seams.
It is possible to unzip these as you would a crochet chain. Instead of pulling 1 string on the back side of the seam, however, you will be pulling a string on each side of the seam. Sometimes this works out just fine (usually when they used actual thread to sew the seam). If, however, they used yarn, most of the time this type of seam doesn't usually want to come apart easily. Often I am forced to resort to snipping each individual connecting thread like I described above. It is very time consuming and annoying. Luckily, most manufacturers only do this on the long seams and the arm and shoulder seams will be crocheted.
So, now we've undone the long seams on each side and our sweater looks like this:
Next we want to take off the sleeves. I usually find the start of the crochet chain at the right side of the armpit, as indicated by the arrow. Remove the sleeves the same way you undid the long seam and your sweater now looks like this:
The arrows indicate where I am going to begin looking for my next seams. Generally at this point, I would remove the neck band. This sweater does not have a neck band, though. It has a double knit edging to the V-neck in the front, and a small seam at the back of the neck connecting it to the back piece of the sweater. I undid the shoulder seams and then that small neck seam. Now my sweater looks like this:
That little piece of double knitting at the back of the neck isn't enough yarn for me to try to salvage and is going to be broken up at the shoulders anyway, so I'm just to cut it off. Each piece of the sweater is going to either have a crochet bind off, or be surged at the top. If it is surged, just cut that part off and pick out all the short cut pieces until you have 1 long strand again. If it has a crochet bind off, you are going to undo it just like you did all of the other crochet seams. Snip 1 of the chains in the chain and unzip it.
You may have a few short strands of yarn at each end of the curved neck shape. That's ok. Just keep unraveling until you're sure that you have 1 long piece.
If you remember, this sweater is a V-neck. 1 side of this V-neck uses the same strand of continuous yarn as the rest of the sweater. The other side joined a new strand at the base of the V-neck. I like to try to unravel the side that is a seperate strand of yarn and ball it up before unraveling the other. The problem is that I have yet to figure out a reliable way to tell which side is which. I usually make my best guess and jump in. This time I got lucky.
Now my sweater pieces are all ready to be harvested for their yarn.
Harvesting Your Yarn:
First things first, figure out how many wraps per inch your yarn is. Do this by taking a ruler, a wpi tool, or a pencil or something with 1 inch marked on it. Wrap your yarn around and around the object as many times as you can in the 1 inch space. Do not wrap too tight, but make sure that there are no gaps. This wraps per inch measurement will give you a good estimate what weight to call your yarn. Use this chart for referance.
There are many ways to unravel and prepare your yarn. Some people simply wind it into traditional round balls directly from the sweater and call it good. This will leave the kinks, or waves still in the yarn. I find that I don't like to knit with wavy yarn. I think it looks sloppy and uneaven and can't wait to block it. I also think that my yarn gets much cleaner if I wash it in skeins than washing it as a whole sweater. The knitted fabric still provides places for dirt and other things to hide while it's still knitted up. Because of this, I prefer to wind my yarn into skeins.
I have wound skeins in many different ways. When I first started out, I wound them around my arm, my leg (from knee to foot) the top of a baby gate, the back of a chair, almost anything that would make a decent length loop. Since then I have gotten a Mama Bear swift that works as a great skein winder and because I completely trashed that one with the amount of yarn I wound, I just got a brand spanking new electric motorized Fricke skein winder. Fancy tools aren't necessary, though. I would measure how many inches around my current skeining method was and then count the wraps as I made them. I like to know the yardage of my yarn so I can plan projects without worrying.
Once your yarn is wound into skeins, tie it in at least 4 places with a figure 8 wrap. It should look like this: This keeps your yarn from tangling up while it's in the skein, and while it's being washed.
Once your yarn is securely tied, fill a sink with VERY hot water and some hair shampoo or wool wash. The hot water is necessary to relax the kinks. Your yarn will not felt if you do not agitate it. Gently push the yarn under the serface of the water until it is all submerged and wet. Let it sit for at least an hour. Gently squeeze the water out and refill the sink with water the same temperature in order to rinse the yarn. If you used wool wash, you can skip this step. Let the yarn soak for a minute or two and then squeeze the water out again. Place the yarn in your washing machine on the spin cycle and let it spin the rest of the water out. Hang the skeins to dry from a hanger. Mine are currently hanging high over a vent, which makes them dry really fast.
-Woolfestival.com has a fantastic wraps per inch guide. It lists generally what wpi equals what weight of yarn, how many stitches per inch, and aproximately how many yards of yarn you will need for a plain sweater. I don't completely agree with the numbers on the wpi chart, but everyone else seems to agree. Maybe I wrap my yarn too tight.
-Mysticspiral.com has some lovely printable yarn labels so you can keep your ever growing stash of recycled yarn organized!
-The Thrifty Knitters Group on Ravlery is a great place to ask questions and get support. You have to be a member of Ravelry.com in order to join, though.
