If you'd like to make your own flower, all you need is toilet paper rolls (or paper towel rolls) and craft glue. Flatten the rolls, cut into bands (a toilet paper roll should give you about four circles). Pop them out a bit so that you have a flower petal shape, and glue together on a flat surface, in any pattern you desire!
Seriously, toilet roll craft is normally AWFUL, but this one is actually very cute! You could even leave off the 'chimney' so it doesn't look like a piece of potentially used toilet paper! ;) Toilet Paper Roll Craft: Advent Calendar via DollarStoreCrafts
