Leaving that behind, I didn't have to look far to find lots of inspiring cardboard tube decorating ideas.
Here's a terrific family tree idea and tutorial by a young mom who blogs from Alaska at No Dime Design. Inspired by an image in a Bed Bath and Beyond circular, she used paper towel/tp rolls to shape branches and leaves.
This pretty wreath tutorial is from Creative Jewish Mom, Sara Rivka.
From The How-To Gal [no longer available], turquoise wall art that she rightly calls trash to treasure.
Jamie from See You There [edit: no longer available] designed this classy wreath that's dressed for the holidays with waxed paper flowers, gold balls, and grosgrain ribbon.
The full tutorial (including how to make the flowers) is on her blog along with this clever idea for a rustic package adornment.
