I am sure you'll do just great! I say never shy away from a pattern that speaks to you. I'm just about 1 year quilting myself and jumped into the Bonnie Hunter Mystery Quilt last November - a quilt that seemed intimidating at first but really wasn't. It wasn't difficult, at all, just time consuming and a great learning experience that set me up for the next challenge! I'm a believer in having the right tools to ensure accuracy and, hopefully, save a little time. There will be plenty of opportunity to use the 60 degree ruler again.
You can do it! Practice with scraps until you are confident and then move onto your beautiful fabric and please share pics with us along the way.
