You will survive and succeed. I am sure.
If I taught myself, I am certain you can learn. I learned from Connecting Threads tutorial.

So far, I have never used a light box to copy my foundation. I make copies to my printer. Sometimes, I will make two copies of a pattern, cut around their edges and tape them onto one page so i can further copy two patterns at a time instead of just one.
Your lightbox sounds great. Happy PP!
