You can obtain the Victorian theme for your tree if you imitate the ornaments of the respective period. The materials used by Victorians included paper, paint, ribbon, fabric and other household items different from the ones used today.
During the Victorian era a popular ornament was the Dresden ornament.

A favorite ornament in the Victorian era was the cone-shaped cornucopias filled with candy. To make your own version you need to curl some colored paper into a cone and glue it. Glue lace or other trim on the open edge. Make more cornucopias and hang them on a ribbon to put them in the tree. Fill them with candy.
You can also use small toys to hang on the tree and bigger toys to place them under the tree. Back any old Christmas card with lace or eyelet trims and transform them into ornaments. Enhance the tree branches by hanging artificial flowers.
