One-of-a-kind dolls should be completely remade–clothes, hair and makeup. Original paint should be removed, and faces repainted with acrylics, then sealed. The entire outfit should be sewn, not glued. And topnotch dolls come with certificates of authenticity. For more info, check out Trish Forte on forteoriginals.com or Jim Faraone’s “Ultimate Fashion Doll Makeovers.” Feel brave? The book can guide you through your first makeover.
