Tunisian Crochet Tutorial: How to Do the Tunisian Knit Stitch
The most important thing in making this stitch is to figure out where you would insert your hook. In the picture below, the blue pin indicates the space between two stitches and the pink pin indicates the space between two vertical bars of the same stitch. The hook is inserted in the space indicated by the pink pin.
Instructions
Forward Pass
Step 1: The first stitch of the forward pass is the one that is on your hook. You do not have to do anything to make the first stitch.
Step 2: Identify the space between the two vertical bars of the next stitch. Insert the hook into that space, yarn over and pull through the space into a loop on the hook.
Step 3: Identify the spaces between the vertical bars in all the stitches in the row. Repeat step 2 for all of them except the last one.
The last stitch is made differently. Find the two vertical bars of the last stitch: the ones in the front and the back. Insert hook into both those bars, yarn over and pull through both of the vertical bars on the hook. You can see a detailed explanation of this step in the Tunisian Simple Stitch tutorial.
Reverse Pass
return pass / backward pass
This is the same as the reverse pass in the Foundation Row.
Chain 1, yarn over and pull through two loops on the hook. Repeat this for all the loops on the hook until you have one loop on the hook.
In Tunisian crochet, the stitches on any given row are defined by how you crochet the next row. The row that was just made defined the one before it as a Tunisian Knit Stitch row.
