I've started casting off my Hornpipe Bag today! :)
For those of you just joining in, my Hornpipe Bag is a double-knit drawstring bag, worked from the bottom up. I'm knitting it in Bernat Sox in the "Rainbow" coloway and Patons Kroy in the "Coal" colorway. It features a knotwork motif on the bottom and which is repeated four times around the sides on alternating backgrounds.
As with all double-knits it takes longer than you originally think. You're literally making both sides of a two sided fabric at the same time; twice the number of stitches as appear on either side. Not quite twice the time to knit but it does add extra time to the process. Of course I have the added issue of having several projects on the go at once; some designs of my own, others by other designers that I want the item or it's perfect as a gift for the knit/yarn worthy in my life. I counted 10 works in progress last week, 6 being my own designs. Ah, the glamorous life of an independent knitting pattern designer ;)
If you're not familiar with double-knitting, I wrote a bit of an overview last year heređź”— on this blog, and I also recommend checking out Alasdair Post-Quinn's site (link in the side menu), Fallingblox Designs.
I'm using a bit of a different cast-off method with my bag, and I thought it would be fun to give a bit of a breakdown here for future reference. This cast-off looks decorative which makes it nice for the top of a bag, or really anywhere you'll be seeing the cast-off a lot, like a scarf end.
For the explanation below instead of alt-captioning the photos, I'll be describing them in detail below each photo for everyone. That way if I need more characters and/or words to describe things it won't be cut off.
So to start, this is a photo of what the first 8 or so stitch-pairs look like cast-off:
Let's back up just a tick. When double-knitting in the basic way with two colors your background will be one color on one side and the other color on the opposite side. Whichever color you knit with, you purl the other stitch of the pair with the other. So here I've been knitting with black and purling with the multicolored yarn for my background. The stitches alternate in the needle, black, multi, black, multi, etc.
Ok, now to work the cast-off. I'm using both yarns as one for the entire cast-off. Knit the first stitch, and purl the second. Now lift the first double stranded stitch over the second and off the needle; this is the usual movements for casting off that you're probably very familiar with. But with double-knitting you have twice the number of stitches and it could splay. (Which come to think of it, would be an interesting way to the shape the bottom of a cowl. I digress!)
What I'm doing on this bag (and other projects in double-knitting) is reducing the stitches to one side's worth and casting-off at the same time.
Ok, we've got one double-stranded stitch on the right needle, originating from one knit and one purl stitches. This is the point the above photo is at.
Work the next pair of stitches the exact same way: knit one with the double strand, and purl one with the double strand. You have three double stranded stitches on the right needle now; right to left: the combined stitch from the previous stitch-pair, a knit stitch and a purl stitch. First you need to create a second combined stitch by lifting the knit stitch over the purl stitch...
... which leaves two double stranded combined stitches on the right needle. Next we cast-off the first combined stitch by lifting it over the second combined stitch...
... returning us to having one double stranded stitch on the right needle. From here we continue the process set out: knit, purl, reduce to one stitch, cast-off the first reduced stitch on the needle.
Using both colors of yarn leaves a neat sort of braided pattern to the top of the cast-off edge:
That's where I'm at with the Hornpipe Bag this evening. Once the cast-off is finished, I can start the drawstrings. Let's here it for i-cord! ;)
Yours in yarn and decorative edging,
