This is one of the older quilt blocks, so it's kind of fun to try to give it a modern look with fabric choices and placement.
Blacksmiths (who used anvils) were big burly guys, so using Seahawks colors, gray, dark blue, lime green seems like a good fit.
Make it 12.5” unfinished, and as always, let the community quilt ladies do the final trim.
he tutorial link for for the block I showed at July Meeting seems to be broken. So I've made a couple from this tutorial. This one seems to give you more choices on fabric placement. Have fun!
