Hello and Welcome!
I would like to suggest - for a beginning quilt - either a nine patch pattern or a rail fence. or one called "Warm Wishes"
I consider myself an advanced beginner or a a novice intermediate quilter - and, in my opinion, a log cabin quilt is a bit more tricky to get each block to be the "expected size" than the blocks I suggested.
Two books that I have looked at more than once -
"Quilts! Quilts! Quilts"! by Diana McClun and Laura Nownes. I think you can get it on a second hand site. I prefer the first edition, because they used fewer fabrics for many of the blocks. Of all the books I have - and I have many - this has been one of the most useful ones.
The other one is
"The It's Okay if You Sit On My Quilts Book" by Mary Ellen Hopkins. I also consider this to be one of the more useful books that I have.
