First some tips!
Turning the pin loom and use the crochet hook
I prefer working on the right side, probably because I’m right handed. So I usually turn my pin loom 180 degrees, so that, after that, I will pull the yarn through from top to bottom on the right side. You can see this in the picture. I also use a crochet needle there. You see that I go under the first thread to pick up the new thread. You can pull the yarn through one step at a time this way if you prefer that.
Here I put my crochet hook under the 3rd warped thread, so that the weft thread goes over the 2nd warped thread.
And here I put my crochet hook under the 5th warped thread, so that the weft thread goes over the 4th warped thread.
Using the tunisian crochet hook
You can also take ‘bigger steps’ by using a tunesian crochet hook. As long as the length of the needle accommodates it, you can go through the weaving process in a single move. In that case, you start at the bottom, by going under the first warp thread, over the next, under the next, all the way to the end. You can then pick up the thread and pull it through in one move (if you don’t loose your thread like me all the time 🙂 ).
If the distance that you have to bridge will even be too long for your tunisian crochet hook, you can also use it in smaller parts. Just look closely to the previous row to see under which threads you have to go!
