Paint a wrapping paper tube white and let dry completely.
Bend a wrapping paper tube into a straw shape. One side should be shorter than the other.
Hot glue the bent part in a few places to help it keep it’s shape. It doesn’t need to be perfect as the cellophane will hold it in.
On a flat surface, lay the straw on top of a piece of cellophane. Fold the cellophane over the straw and trim the folded edge so you have two equal-sized pieces. Use double stick tape to seal all the edges.
Use hem tape to attach the straw to the dress.
