Hi Sandra, here is the link to my sample using 8/2 cotton in yellow and green with a couple of ends of shetland in the white.
One photo shows after washing for about 7minutes and letting dry. I wanted more shrinkage for contrast so washed it again for 5 minutes. I set it at 12 epi. A bit challenging to weave at 12 ppi! I warped 12 ends of cotton (6 each of the yellow and green) and put 2 strands of wool between.
It's very cool to see what happens to the different yarns after washing. Any feedback is most welcome.
