Greetings from Northern California. My first attempt at quilting was a sampler class from the book Quilts! Quilts! Quilts! I REALLY appreciated it because it taught me all the terminology and all the finer points like 1/4" seams, accurate cutting, accurate pressing, and a host of other helpful hints. There were quite a few blocks I liked and WAS SURE that I would make a whole quilt out of them. After ONE block - I would change my mind on many of them.
Often we collectively recommend to a beginner (or "newbie) that they start with a manageable size and an easy pattern. Anything with triangles is not necessarily for the first lesson. BUT, that said, I agree with Alicat, do a test block and see how it works out. And if the first one doesn't try it again. None of us were experts out of the shoot. Most importantly - have fun with it.
