Illustrator background issue
I have downloaded a vector of a doll figure and I want to replace her hair accessory with a different one. However, when I remove the current hair accessory, the shape of the accessory seems to have been cut out from her hair (so when i remove the green berry leaves, it reveals the purple background instead of brown hair). How do I revert the hair to how it was before it had the shape cut out of it?
