I'm working on Jinny Beyer's Crystal Star large size but they have the 25" pattern too. I saw it at a friend's house over her mantel and I just had to have one too though I don't have a mantel and have never tried paper piecing before. I'm at the point of putting the sections together to finish and it wasn't as difficult as I'd thought it would be. The pattern comes with both sizes and directions if you want to use your own color scheme instead of their 150 colors as on the front of the pattern.
I'm also a fairly new quilter and if it is easy for me, anyone can do it.
