That is an extraordinary quilt...if I liked doing applique I would do it and I am no where near intermediate.
Just take your time and know this quilt will take real time to complete!! cheering for you!

Sindy Rodenmayer does do fabulous work doesn't she? I was able to start saving the fiesta blocks with #3 (missed #1 & 2). I've just gotten EQ7 so haven't had much practice with it (meaning only cracked the book open and loaded program onto machine) but I will be taking some lessons starting in September on it via online. So is having the files easier or what with the EQ7 files than the PDF files she has available? Aha, I see that she now has both formats available for sale. But please tell me why would I use the EQ files? Is it just to see fabrics or with the printing of the blocks out or what? You have me curious as to what I've been missing without having this program before now!

Try one block. If it turns out that you can do it well, then keep going. If it turns out that it is a little too challenging yet, then make it into a pillow. You have nothing to lose and lots of experience to gain.

You can re-size the blocks (bigger or smaller), play with alternate settings, see them with different fabrics, intersperse different blocks and see how they play with the originals, change the blocks... so many options when you have EQ.

I think Fiesta looks harder to me.

I think it's painted. Looks like fun. I watched a Fons and Porter show a couple of weeks ago and the quilter painted blocks. It was really beautiful. I've been wanting to t ry it myself but don't have any good design patterns. I'd go for it.

Here is a link to a block of the month for a similar type--free-- you could try a block....http://www.fatcatpatterns.com/Fiesta.html

it's a beautiful quilt, I say just start and take your time. I made a complicated one by just taking one block at a time and before I knew it all the blocks were done and I gained confidence with each block.

Looking at it I see two things that make it "advanced". One of the narrowness of some of the pieces, but even more difficult is the closeness of the appliqued pieces to each other - a lot of them are right next to each other.

I would say try to make a few pieces of your own. Try the fans with the long narrow curves placed at a point at the center and fanned out at the top. Also try a few pieces where you place two pieces butted up to each other (unless the technique is to applique one on top of the other?).

So try making your own. Just use a few pieces scrap and cut them as close to some of the shapes and place them similarly to the shapes.

One other thing if you decide to go for it. I see that a lot of the pieces, especially the fans, look like hand dyes with graduated hue. Not sure if that will be important to you or not to achieve the same affect.

This pattern is for someone advanced in applique.
Not a pattern for a beginner. If you are a beginner and try such a complicated pattern I'm afraid you may not finish the quilt or
muddle through and not be satisfied with the finished quilt top. A lot of time, work and money will go into applique quilt.
Be sure you are up to the challenge. I would do some smaller project until I can advance to this pattern.
