I'm in the process of making another Barbie wig. I realized that fabric glue is better because I can wash the wigs without ruining the bond, unlike the regular glue. The cling wrap is to protect the doll's face from the glue.
I really like the facial screening aesthetic of some of the collector Barbie dolls starting from the early 2000s, specifically the small iris on the eyes. I had to recreate it with the current Barbie Basics.
The first series of Barbie Basics from 2009 had that detail. In the latest line, starting from 2025, only some had small irises.
