When it comes to increasing and decreasing in double-loom knitting, it’s easier than you think!
You’ll want to do this at the beginning and/or end of the row.
Following is a quick video as well as written instructions:
On the back board, take the previous stitch from your last stitch and bring it over to the next empty pin:
Do the same on the front board:
You have now increased your work by one stitch. If you increase on both ends of the board, you will increase your work by two stitches.
Take the loop at the end of the row and move it to the next occupied pin. You now have two loops on the end pin. Do the same on the back side of the board.
After wrapping your next row, you will have three loops on the two end pins. Hook over the bottom two loops leaving one loop left on the pin.
You have now decreased your work by one stitch. If you decrease on both ends of the board, you will decrease your work by two stitches.
