Sorry, my question may not have been clear.
Sometimes when I make a scarf I wrap the wool around the needle twice, thus creating an extra stitch. I then drop the extra stitch on the next row making a nice big loop. Or you could knit the extra stitch.
When you do a YO, instead of the wool behind the needle, it's infront and wrapped around once, which also creates an extra stitch.
Is the end result different with these two stitches? Instead of doing a YO where the wool is infront of the needle, could I just leave it behind and wrap around twice instead?
I learnt the technique of wrapping around the wool twice before I learnt how to do a YO (which I learnt from the video on this site)I've done about 20 rows of my scarf now using the YO and have got the hang of putting the wool at the front, but because I don't hold my wool properly when I knit, it would be easier to just wrap it around twice if the end result is going to be the same.
Does that make sense now?
