You might have noticed that styles are changing and things are not as matchy matchy as they once were. Contrasting fabrics used together are becoming quite popular. I'm not sure what this new trend is called, but while I find it refreshing it can also be a little overwhelming if over done.
I normally wouldn't have considered any thing other than the shirt fabric for the neckband for the shirt, but a messy cutting table led me to try something different. The blue gingham gives an otherwise plain shirt an updated look. Why not pull out some of your leftover pieces of fabric and see what you can match up?
