A weird thing about Tunisian crochet is that the flat and in-the-round variants are quite different from each other! Flat uses a singed ended hook, and round uses a double ended hook. Flat builds up stitches on the hook in one direction, and removes them from the hook in the opposite direction. Round builds up stitches in one direction, and removes them in the same direction, but off the other side of the hook. There are patterns you can produce in round that seem impossible to do in the other, and vice versa. Here, I’m trying to guess at one possible flat method to mimic this traditional in-the-round pattern.

So, intuitively it seems doable the standard way, at first. The beginning goes easy enough. You work forward in yarn color A, then tie in yarn color B and do your return pass in that. Now, you go to do the next forward pass, but gasp! The working end of yarn color A is still over on the other side of the work! You left it there when you tied on yarn color B.

One attempt I’ve seen done is to carry the unused yarn along the back of the work, but it’s messy and makes for a loose fabric. I went another method:

How this goes is, you use the double ended hook you’d usually use for in-the-round. You pick up and remove stitches with the two ends as you would in the round, until you get to the other side. This is where it gets weird. Now, you do that exact same thing over again, except you do everything in reverse! The side of the hook you were using to remove stitches, now you’re using it to pick them up. And the side you were using to pick up stitches will remove them. It doesn’t feel great or intuitive, it’s basically like switching from left handed to right handed or vice versa.

It works, but as you can see there’s one more problem. The vertical ribs in TSS always tilt slightly to one side, but now the tilt direction changes each row! There is a way to fix that using twisted TSS stitches on alternate rows, but to make it more complicated, I also wanted to have a solid color border at the left and right. This is roughly how I thought it could go, combining this new method with the float method mentioned earlier for the sides:

So, incorporating all this, I tried it again. Here’s the comparison, with LOTS of mistakes. It was eally hard to get the hang of lol. Check it out:
