I cut these butterflies, and hands out of paper, spread gum on them and sprinkled glitter. Then I pasted them on these CDs with Fevicol.
I did not fold them at all. They were straight the day I made them.
Deformation started the next day. I stuck the big hand's finger on wall with a tape since that was the one that bent forward the next day. Now, after nearly 5 months all of the hands are deeply curved, so are the butterflies.
Sticking them to the wall has the demerit that it makes the craft immobile (I live in a rented house).
Why did they deform? What all choices do I have now for such future projects?
