Easy decrease

1. Pull a loop through the next stitch (2 loops on hook).
2. Insert hook into the next stitch and pull a loop through (3 loops on hook).
3. YO and pull yo through all loops on hook. This is an almost invisible decrease.

Diagram above shows front decrease, principle applies to all stitch variants.

1. Skip a stitch.
2. Insert hook into the stitch after the skipped stitch.
3. Insert hook into the skipped stitch.
4. YO
5. Draw YO through all loops on hook. (Ending in one loop on hook.)
