The construction of the baby blanket is exactly the same as the napkins I made a while back and is very fast and easy. I used a piece of black and white flannel with the Star Wars logo and a piece of quilting weight cotton depicting various contraptions (sorry, not familiar with the technical terminology) from the movies. I whipped up two blankets in an afternoon. (In the photo, the blanket is folded in quarters.)
You can see what the mitered corner looks like below. Don't be afraid; super easy...just follow the directions in the tutorial.
While I'm sure the parents are going to love the Star Wars theme, if I was making a blanket for another recipient, I'd go with this or this or this. A couple of custom blankets paired with some board books and I am ready for the baby shower!
