Since this will be a work tote with sharp, pointly plastic binder ends and such, bought stiff canvas and cut/resized cardboard for the base.

I intend to write a fair-isle pattern in the future, but needed to see a completed design first!

Bag of choice (canvas or yarn)
Yarn: crab red and black, bee black and yellow and white.
Cotton thread or other sewing thread

Mixed knit and crochet crab and bee and sewed on
