This morning I worked on my Volks Chii.
I tried using hot glue for both wig + persicom ears but it didn't work (apparently it doesn't stick to Soft Vinyl) so I had to resort to Super Glue even though PrincessD adviced against it

Here's keeping my fingers crossed it won't ruin her head!
I'll keep you posted.
But oh she looks better (at least to me) & it's such a relief not to have to worry about her wig coming off.
Btw I glued the velcro to her scalp, I figured it was wiser than gluing the whole wig to it.
Thanks to Poohki & Princess D for their replies!
Note: my Chii is a Volks Dollfie (27cm), the body is made with durable plastic & the head is made of Soft Vinyl , I used regular craft foam for her persicom ears.
I think next time I'll try to use all purpose craft glue
