These are Smellis, named after their inventor Smellihelli (who needs to update her blog). They are made using a 10cm (4 inch) protractor as a template. These were done for a swap organised by Helli on the DoCrafts forum,
with the idea being that each person in the group chooses a theme and everyone makes them a Smelli on that theme and sends it to them. These are my Smellis on the themes of oriental, garden quotes, travel and buildings.
