What do I do with the chrysalis?

I purchased a butterfly kit for my class room with 5 painted ladies. They have each formed a chrysalis on a napkin and are inside the 1-cup container they came in. How can i move them to the butterfly house and on what should I put the napkin to which all five are attached so when they emerge, they will not damage their wings?

Karen says:

If it is possible, could you maybe tape the napkin to the top of the butterfly house? Even taping a corner of the napkin so that the chrysalis are somewhat hanging free and there is room for the butterflies to spread their wings. Hopefully this helps.
