Talk about the double meaning of the word “matters”! Tension matters could mean discussing things about tension, but what I really mean is that it matters! It is terribly important to your knitting success. I think that the majority of beginner’s problems start with yarn prep and tension, which is why I am returning to this topic again.
Last time I talked about preparing the yarn to flow smoothly. Well, that carries over to the tension unit too! You want the yarn placed directly below the yarn guide of the mast and then you want it to pass straight through the various guides and discs without looping back on itself.
First and foremost, if your tension dials have numbers on them, stop looking for a magic number and start paying attention to how the unit functions. The tension mast serves the same purpose that wrapping the yarn around your index finger serves in hand knitting. The idea is to avoid loops at the edges, tight stitches at the edges (or across the row) or dropped edge stitches. Poorly adjusted tension will never produce even rows of stitches.
One of the problems with having numbers on the dials is that the numbering system differs from brand to brand and even from model to model. For some machines a number “1” indicates the tightest tension, which you would use with very fine yarn (little number=thin yarn). On other machines, however, it indicates the least amount of tension (low number=low tension for thicker yarns).
If your manual isn’t handy or you have a momentary lapse, thread the mast and catch the end of the yarn under the clip to hold it. Then pull down on the yarn below the yarn guide until the wire touches the last threading eyelet or guide. If the wire stays down, then “1” is the tightest tension on your dial. If it flies back up, it is the loosest. Neither setting is what you ultimately need, but you do need to know which way to turn the dial!
The Correct Tension is one where the wire is able to lift up any slack at the beginning of every row and then drops down as you knit across the row, ready to lift up at the start of the next row. If the wire is not able to pull up edge loops, the tension is probably to loose. If the wire stays down near the eyelet throughout, it is too tight.
The reason you need that up and down bobbing has to do with the distance between the edge needle and the center of the carriage, which is where new yarn is fed into the needle. That distance can often amount to 5-6” of extra yarn that must be pulled up when the carriage starts to move. Otherwise, you get loose edge stitches, dropped edge stitches or yarn wrapped around the brushes and wheels and gizmos under the carriage arm/sinker.
If you make note of that action, you’ll take control of the tension and feel like an empowered knitter! When things do go wrong, the tension mast is the first place I look. Sometimes the yarn may have worked itself out of a guide or maybe it wasn’t actually under the pin and between the tension discs to begin with. Re-check everything.
Also, you can avoid tangled yarn mishaps if you get into the habit of only leaving short (2”) tails clipped to the mast. Longer lengths whip around, build up static electricity and eventually mate up with the yarn you are using until both of them are jamming their way through the tension discs and the carriage comes to a grinding halt. Wonder how I know so much about that…….
One more thing! If you would like to thread multiple yarns through several masts, there is a free download on my web site (www.guagliumi.com) entitled “Multiple Tension Mast Holder”. It works like a charm for busy stripes!
