Strands of yarn strung through perforated paper (on the left) and from wire (on the right) make novel beards for these Santas. Found at Peikonpoika, there's not a lot of detail in how they are made but enough to get you started on this cute idea.
Once kids master making i-cord there are lots of things that can be made from it. Krokotak shows you how to make a knitting knobby (also known as spool knitting or corking) from a toilet paper roll and popsicle sticks.
Little ones will need to have a collaborator for this autumn string art, but that makes it a perfect project for side-by-side crafting. This would be a great addition to a leaf study or wall art to celebrate the season. Details are at Crafting Connections.
