If your knitting is tight and you’re having trouble lifting the yarn loop onto the left needle, try using your fingers to move the loop.
Knitting through the back loop will create criss-cross V shapes in the stitches. It will also prevent gaps from forming between the increased stitches.
If you have a hard time using the needle to move the loop, you can use your fingers to slide the loop onto the left needle.
Even though you’re knitting this new stitch as usual, it will feel a little tighter because of the twist. This slight twist will prevent a hole or gap from forming between the stitches.
