This entirely depends on the paper mache ideas that you choose to make. Different objects and sculptures require different bases and forms to support them. Regardless of that, here are some of the commonly used forms or bases in paper mache ideas: - Balloons are useful for making masks, sculptural faces, and bowls. - Square things like jewelry boxes and planters are best made out of cardboard. Cardboard can also be used to create elaborate frames for sculptures and pinatas. - Flexible wire can be used to make large-scale constructions, such as lamp bases or lanterns. - Eggs are usually used as a base for miniature dolls and other smaller items. If you wish to freehand without a base or mold, produce some paper pulp. You combine entire sheets of paper with water to create pulp by blending the mixture until it resembles pulp.
