You can do it! We're all here for you when you have questions!
My advice would be to take it one step at a time. Don't read too far ahead and then get overwhelmed and put it aside. If you're unsure about a step, try it with scrap or muslin first. Sometimes when I'm working with a pattern and don't understand the instructions, they become clearer when I actually walk through them with scrap fabric.
I can't wait to see your pictures! I love her quilts, they're so vivid and happy.
