Here is my plastic only sit-upon without the denim. This is my basic recycled plastic sit-upon that is crocheted using plastic bags made into plarn and with a fused plastic backing. This fused plastic backing makes the sit-upon waterproof.

Here is the back side of the finished sit-upon and also another version of how you can decorate your finished denim side by adding a denim jean pocket.

I tried to keep this project simple so a young Girl Scout or anyone could make this sit-upon without a bunch of sewing required. You can just glue the hearts on or even hand decorate the denim. Handwriting your name on the denim may be another embellishment a Scout could add. Needless to say, you can decorate as much or as little as you like. I’ve included several different ideas and here is the free crochet pattern and tutorial on making a recycled sit-upon.
