I felt the same as you with my first bargello. I had chosen all my fabric and kept putting it off because I thought it would be really hard. But once I got started it was really not that difficult. The main thing is keeping your strips organized. I made labels for each of the strips that were numbered according to the pattern. As I cut each strip I pinned on its label. Then I laid all of them out in the order they needed to be sewn. And I didn't cut all the strips at the beginning. I cut a few and sewed them together as a test. The hardest part is getting started. Don't be scared. Just dive in. Bet you'll end up with a beautiful quilt.
