1) Emotions (anything that depicts an emotion so could be anything from a clenched fist to a giraffe crying

2) Boxes/Containers (an object that can contain something - could be a vase, tray, bowl, box etc. but plates wouldn't be allowed because they don't really have sides

3) Flat tessellations (a tessellation that is 2D so no puffy out bits!

Rules: I nearly always use one square sheet of paper with no cuts or glue but if you prefer I'm happy to agree with one rectangular piece of paper and for boxes/containers also allowing modular designs and regular polygons e.g. hexagons, octagons, pentagons - let me know what you think!
We will have 20 days to design and post our models from 1st February and can submit as many entries as we like.
Hopefully I have supplied a good range of interesting topics, can't wait to see what you decide upon and design! Good luck!
