Do you do anything special to your threads before putting them through
your fabric to make them more manageable?
For ordinary or overdyed flosses, no. For rayon, I swipe it with a very slightly damp make up sponge - it helps stop the kinkies. For metallic braid, I don't use anything, but for metallic stranded floss, I use Thread Heaven (when I can find it). Also, for metallic floss, I use shorter lengths and knot it to the eye of the needle.
