left twisted stitch
LT stands for left twist, and creates a twisted stitch that leans to the left. It can be a little fiddly to begin with so watch carefully.
Here’s how to work it : insert your right needle into the back loop of the 2nd stitch on your left needle. Wrap your yarn and draw a long loop through, now go into that first stitch on your left needle and knit as normal. Drop the 2 worked stitches off your left needle.
