Do roving-painting. You give each child a flat piece of felt and lots of different colours of roving and have them take tiny pieces of the roving to stick to the felt in a picture. We made pictures of apple orchards last week and my boys (6 & 4) had lots of fun.
Maybe do some simple cooking projects? Apple sauce, make apple rounds and dry them for Winter, make an apple pie.
Check out the Michaelmas thread for some ideas for Michaelmas-related crafts.
I'm working on generating ideas for a hat project. I'm thinking I want to make the boys felt gnome hats and then let them do the wool-roving painting on them, then I'd needle-felt their designs for them. Not sure if that might be too labour-intensive, though!
Our homeschool group is working with a Waldorf teacher, and our first two classes taught rope-making (you take three strands of wool and string them between two partners. Twist until really tight, then find the middle, hold the two ends together, and when you say 'Magic!" and let the middle go, the yarn twists itself into a rope. Hope that made sense, I couldn't find a tutorial in a 10-second google search). The other project we did was finger-knitting. I plan to curl up the boys' first finger-knitted lengths to make simple snails.
Have fun! Let us know what you come up with...I know we're always looking for great ideas at our house.
