Hello, I was gifted a lot of 10/2 unmercerized cotton that I would like to use as a warp. Most of Jane's instruction is in regard to achieving a balanced weave. Are there guidelines for combining different weights of yarn in warp and weft? I would like to use 10/2 for warp and 8/2 for weft. Conversely, what about combining 10/2 warp with a thinner weft, like 14/2? How do I start the planning process?
