I just Google the pattern and to me, it looks like a very complicated Wedding ring. Very pretty. But you have a lot of experienced quilters on this board that can help you thru the process. Yes, I believe you as a beginner certainly bit off more than you can chew but we are more than delighted to help you through the process.
1st question is can you sew an accurate 1/4" seam?? That is going to be most important when attempting this kind of complicated pattern. Make some way to mark on your machine bed. I use that blue paint tape to make sure I am on my mark for an accurate seam.
Can you print out a block and the cut small pieces of the pattern and glue (glue stick) them onto the printed pattern block?? Yes if you think another background would work better for you, go for it. This is what I do when I am concern with the placement of colors in a quilt block. You are NOT the village idiot. Let us get THAT straight first. But try to do a sample block even if you have to do more than one so you have a "plan" that you can refer to.
Please keep posting.
