I was talking to my mother-in-law about her super saturday coming up in Relief Society and this was a project we did at ours last year. I was going to send her an email with instructions, but a blog is much easier. Plus I thought someone else might like the idea.
Materials needed: roll of toilet paper, fabric, brown lunch bag, twine, straight pins, tape.

Tuck the ends of the fabric into the middle of the toilet paper roll. Use straight pins to hold the fabric.

Take the brown lunch bag and roll it up to desired length and width, secure with tape

Wrap twine around half of the bag.

Push paper bag into center of toilet paper roll

Add fake leaf if desired.

You can also use a paper towel roll to make a tall pumpkin, or two toilet paper rolls stacked on top of each other. These make a cute holiday center piece.
