Hi Lab Rat,
That's really kind of you to offer to send them out in the post, I may take you up on that if that's ok.
Is it at all possible to carefully remove the existing pupils, leaving them intact to re-place? I think I read somewhere on here that they fall apart if you try to peel them off?
And your pictures are fantastic, thanks again.
Regarding the sticky black velour roll from Hobbycraft, it's not quite the right material, it doesn't have the thicker texture that the actual pupils have but you'd have to be a pure perfectionist to notice, but I guess the fact that we're all talking about changing them shows there's quite a few perfectionists on here who want their Muppet posers to be just right, & who can blame us!
