I found these on You Tube -
Her loom is warped with three heddle bars with looks to be a diamond twill. You can also clearly see how she has used packs of cards on either side to add a selvage edge to the fabric.
In the second video you can really see how important the pin beater is to scallop the weft up - especially in a wide and more complex pattern like she is weaving...
Parking these here so I can watch them a few more times :)
