Sandi,
Happy birthday!!!!!!!!!!!!!!!!! Sorry so late.
I think you'll really like the booties if you've not found out already. I love making socks! I've not done it on multiple straights, the two circulars work good for me. But I really really loved making the one pair I've made. I will do more once I get some yarn for socks. So, much success to you in doing the booties. I bet they'll be adorable!
Nancy
