Doll cotton is suitable for making toys and soft decorations, but it is not suitable for filling materials of sofas. Sofa needs to have some support to keep its shape and comfort. Doll cotton does not have enough elasticity and support, and will collapse and lose its original shape after long-term use.

　　The filling material of sofa should be high-density foam or spring, which has good support and elasticity, can support the weight of human body, and is not easy to deform or collapse after long-term use.

　　Filling doll cotton is good.

　　Because doll cotton usually has good elasticity and warmth retention, the quality of its filling material determines the feel and appearance of the doll.

　　In addition, filling doll cotton is also a very interesting manual activity, which can make people relax and improve their creativity and practical ability.

　　However, it should be noted that the filling should be uniform, not excessive or insufficient, otherwise it will affect the appearance and use effect of the doll.

　　Therefore, choosing good quality doll cotton and filling it skillfully will bring people a better experience.
