There are two key pieces to making a decrease invisible.
- Number one -- instead of working in both loops of the stitches from the previous round -- you work in just the front loops.
- Number two -- You do not yarn over (YO) before picking up the first and second loops.
To begin an invisible decrease, poke your hook through the front loop of the first stitch you're decreasing.
Then, without doing a yarn over, poke your hook through the front loop of the second stitch you're decreasing.
Now, you can yarn over and pull through all three loops on your hook. Can you spot the decrease in the round I just finished below? Me neither!
