i was going threw a pattern when i came across this bind off. I never heard of it before so i did some research. i could only find one video on this. but a few tutorials. so i thought i would share.
this is merged two different bind-offs; the Icelandic bind-off and a picot bind-off.
1b: While the right hand needle is through the first stitch, the second stitch will be pulled through the first stitch. The stitches have switch places on the needle.
STEP 3a / Return the just knit stitch on your right hand needle back onto the left hand needle. knit this stitch again, creating the appearance of a chain.
STEP 3b / Once you have knit the first stitch a second time, leave it on your right hand needle. Then, knit the next two stitches on the left hand needle together. You have just decreased 3 stitches down to two.
STEP 5 / Return the stitch to the left hand needle. This step is critical: if the stitch is not returned, you will amass a large quantity of stitches that are still "live" on the right hand needle.
Repeat Steps 1-5 for the desired number of stitches, or until all your stitches have been bound off.
there is a cast on for this. and if i get time i will post it.
