Why is this important?
Because many of the methods out there I tried do not account for this, which can make it a bit tricky when working the following round.
Once your last stitch is completed [photo 1], cut your yarn, leaving at least a 6 inch tail.
Depending on the type of yarn you are using you may need up to 10 inches to work comfortably with.
Pull the end right through [photo 2]
Thread your tail end through your yarn needle.
The red arrow in photo 3 shows your starting stitch, or chain start, with an invisible join you are going to make a “false” top to this stitch and cover it with the invisible join.
The green arrow is pointing to the 2nd stitch, this is the stitch you will join to.
Insert your yarn needle, from back to front, under the top loops of stitch 2. [photo 4]
