Well, I finally did what I've read about respinning. I knew that my singles were not strong enough to hold up to the weaving tension once they were plied. I finally reread the information about energized singles and the fact that they make great collapsible fabric when used as weft. I then learned that those same over twisted yarns when cabled or plied make for a very strong warp. If you are cabling (4 strands, 2 plied and 2 plied, then spun the opposite direction of the plying to get all 4 strands in a strong cabled yarn.), the only advice I can offer is that the strands be very thin and over energized as singles. This makes for a light weight cabled yarn. If you want a yarn that is thicker, then increase the twist and the size of each strand. This makes for a very knit-able yarn. I haven't made cabled yarn for quite some time. I turned all that I made into necklaces with natural pendants and they have all been sold. I was surprised to find I am all out of that yarn. I need to make more and now is the perfect opportunity as I am spinning the silk and camel. I really like the consistency of the blend after I respun it. Photos of the single are below. I will post the one yarn once it is cabled as well so keep in touch if you'd like to see the finished yarn.
May we all find time in our busy lives to enjoy the art of spinning!!!

This is what the single looks like when I let go. The one below is with tension on the end of the string to keep it from plying. And the final photo is of a close-up of my cabled yarn with the ribbon for a necklace. Happy Spinning and Weaving! Liana
