Garter stitch (every row is knit) can be very easy to hide short rows in as it looks like a series of ‘bumps’ when you are working it. However if you are working at a loose gauge and if there are a lot of short rows they become more visible and can make your knitting look uneven with gaps.
German Short rows work really well in Garter Stitch. They are simple to work and they are not too visible from either side of the work.
Step 1: Knit to the turning point and turn your work.
