The last time I made anything with my Weavette looms it was a total pain in the ass, but ultimately worth it because my niece apparently liked the little purse I made. But I broke TWO needles making the thing. What a difference wool makes! Unlike cord, wool has some give, so instead of pulling the needle through with a pair of pliers, I am able to gently pull it, with no fear of bodily puncture. Anyway, here are the steps to pin loom weaving. This is a semi-secret project, so I won't say what this will ultimately be, but anyone who knows me will take one look at the color of the yarn and know I'm making it for myself.
First you warp the loom, going back and forth, then turning the loom and going back and forth again, then turning it back to the original position and filling in the gaps.
Then you fill in the gaps in the other direction with the needle.
And voila! Many little squares that can be sewn together. This is a 4" square loom.
