One of my favourite provisional cast ons is the crochet cast
on where you crochet the stitches directly onto the needle with waste yarn. I
like this method because it is easy to execute and your starting stitches are
securely held until you need them. Although I also like Judy’s Magic Cast on as
a provisional cast on, it has the disadvantage of a spare needle/cable etc
flapping around plus this cast on is effectively creating two rows which is
fine for stocking stitch but not if working in a pattern.
Knitters say they do not like the provisional crochet cast
on because they have trouble taking it out and putting live stitches on the
needle. Recently I was about to undo a crochet cast on and I decided to take
photos to show how easy the unzipping is once you know how. I did not think to
take pictures of me working the cast on which I will have to rectify if not on
a real project but on a test piece.
The secret to making this easy is to know at which end to
start. When you have completed your provisional cast on, start knitting with
the main yarn at the same end as you finished the cast on. Then when it is time
to unzip you will start at the end where your yarn tail for the main colour is.
No tying knots or working additional chains to help remember which end is which and then trying to remember what those knots/chains indicated.
Here is the first picture showing the
provisional cast on and the knitting - and some errant cat hairs.
I think where knitters get confused is that they think they
can just pull the end of the waste yarn and violà there are all the live
stitches; when that doesn’t happen they go to the other end of the piece and try
there and end up in knots. But if you think about it, it wouldn’t be a very
secure cast on if one pull on the thread revealed live stitches. First you have
to release the first stitch; in effect unknotting the yarn. You pull the end of
the waste yarn out of the last loop.
This picture shows where I am starting to
do that and the next picture shows the end released and the first provisional
stitch.
Now all you have to do is pull on the end of the waste yarn and live
stitches appear.
Here it is as I am about to reveal the first live stitches.
With this type of provisional cast on, it is a two step process to get the
loops of the main yarn. If you use a small gauge needle you can slide the
needle in to the main stitch before the waste yarn is pulled out, creating a
layer of security, especially useful if working with fine yarn.
Continue this way until the last provisional stitch; you don’t
want to get so excited at the zipping that you miss your last live stitch. (The
loose stitch in the photo is a yarn over as I was working a lace pattern.)
When you have dealt with the last stitch, your provisional
yarn will be caught in your knitting as shown in the next photo. This is actually
your last stitch and should be placed on the needle.
And that’s it. I hope this has demystified the provisional
crochet cast on for those who were having trouble.
