|Sometimes I’ve seen bad twists within the raddle groups–as though the yarns wrapped around themselves within each raddle group. This happens with certain yarns–ones that are unbalanced. Singles yarns are often unbalanced, but plied ones can be, too. Yarns that appear balanced can be seen to be unbalanced when they are put into hot water.
How to Avoid Bad Twists:
Be careful when beaming the warp. Watch the sections of warp as they go from the raddle to the warp beam–are the yarns twisting around themselves in the groups? If so, work your fingers through the section to untwist them and make sure they are going onto the beam in a flat, untwisted “ribbon.” See figure A If you have a very unbalanced yarn, you’ll need to do this diligently so no twisted sections get rolled onto the warp beam.
There is more of a chance for the yarns to twist the farther away the raddle is from the warp beam. Say, if the raddle is on the castle as in Figure B.
