Here we go:
I began by CAREFULLY cutting out the worn area, being sure to only cut through stitches necessary. In this instance it is a worn elbow spot. One of the common wear spots, especially if you are in a desk job and use a mouse most of the day. With machine made sweaters, each of the stitches are connected to the next. This means a little extra work. My intentional cuts have broken the line or bond.
If your sweater owner didn't keep the extra yarn that came with purchase, here's a tip. I took the "cut out" with me to the yarn store to find a close match for the repair. I didn't find a match in my first stop. Luckily my town has several stores that stock a variety of yarns. My third stop, I found a close match. Whew!
So as to not lose the stitches I used a darning needle and thread to hold the lines. Here is a closeup view for reference.
In order to re-weave, I need to pull out some more stitches. I am actually going to make the hole larger. The "hanging threads" will be woven into the garment at the end to create a seamless patch.
I have used # 4 sock knitting needles to hold the stitches and bobby pins to hold the loose threads.
Now it is time to knit up a piece to fit into the hole. Use the sweater gauge as a guide. You may have to knit up a couple different patches before you have the right gauge. If you are an advanced knitter you can measure the stitches on the sweater to calculate your gauge. ie x number of stitches per inch = a certain size needle.
