Gemm --- Nice finish and nice design to add to your repertoire. As you've found out there is a lot of fabric in (especially a large man's) shirt!
One of the fun things that can be done with that block and others like it that are also basically HST like a log cabin is the many ways you can set the top. When I moved I donated most of my books. One I kept was Judy Martin's original Log Cabin Quilt Book -- back from the days of templates and not rotary cutting directions but with a lot of great information.
Here's a page I found that gives some of the overall layouts --

For me -- well, I said I would be buying some fabric this year for a specific set of projects and I did -- but while I was there at the fabric store I didn't buy a slightly better back for my Bonnie Hunter mystery this year. I had a nice dark royal blue in my stash that will work fine even if it isn't quite the navy or indigo blue of the top. Nor did I buy anything not on my list although some of the sale fabrics tempted me greatly -- especially one with donuts, maybe I was just hungry??
Edit: When I tested my link I had sort of a different result from my first view with a "view slideshow" option. At the top of that is a "view all" button which I liked much better.
