How should I plan for teaching a textiles course for 7-10 year olds?

Okay, starting Tuesday I will be teaching a childrens’ textile course in my hometown. The course covers dyeing and embellishment, and meets once a week for 4 weeks with a 2.5 hour class.

I’m pretty experienced with textile dying, but I’ve never taught it before, much less to small children. I’m planning on covering tie dye, embroidery, simple stamping and resist dyeing… But how I should organize my classes is baffling me and I’m getting a little nervous!

So, does anyone have any suggestions for me, about teaching textile arts or just teaching children in general? I would really appreciate your help. Thank you!
