Career Day

I'm going to be giving a career day presentation in Carly's class tomorrow. I'm sure your all thinking 'What career?' What can I say, they were desperate, actually when I mentioned that I could come and talk to the kids about sewing, her teachers thought that would be really neat. I have lots of visual aids so I think the kids will be pretty interested. I'm going to bring some quilts and some clothes, and lots of my tools. Is it weird that I'm a little nervous to get up in front of 5 year olds?
