If the silk is stuck, you may need to carefully wet it to loosen it. I've taken a stick pin, put it through the silk, lifted it off its current location, and pinned it in better location. You could even pin it to a leaf. I've also taken an old pupa and taken the silk from it and added it if you think there is not enough silk or cottom from a cotton ball or q-tip. Wherever you put it, don't hang it too high and put a paper towel with wax paper under it in case it falls--cushion and something it won't stick to.
