I do not know which material you use to make the eyelids.Karrot wrote: anyone with any hints on how to secure them overnight?
In my case I have chosen some soft felt they had at the trade shop and that stuff has a surface full of little fluff or lint (I do not know how to describe it exactly), and because of the fluff it is quite adhesive to the smooth plastic of the eyes. So I did not need any extra kind of glue to make them stick (and I do not feel I can recommend any kind of glue, because I would be afraid the eyes could be damaged when trying to remove the eyelids).
With that find of fabric after putting the eyelids on, the sleep spell was that deep that I could hold the doll up face down and even shake them (very gently) and the eyelids did not come off at all.
So I guess it is all in the material for the lids; the fabric should just not be too smooth, so it created some "natural" adhesion, and that is all what is needed. Uh, I hope I have been understandable at least a bit.
