I bought surgical scissors with which to cut the loops open. Instead of cutting the loops under tension on the loom, I cut them after I had removed the samples from the loom. The cut pile looks like this:
The loops are made from 6 strands of 2/28 cashmere in various colours. I mixed the colours as I went to achieve an interesting gradient. You can also see the strand of 2/16 silk in hand-dyed variegated teal, which I interspersed with the pile bundles. I will post another picture after wet finishing, when the bundles turn into rows of fluffy topiary.
