Baby Blanket

While I was looking for the perfect fabric for the blanket I'm making my best friend, I found the perfect fabric for me! I found flannel giraffes! Yay! It was on the sale rack at Walmart, so I had to buy it.

Now that I bought it, I'm trying to figure out what I want to do with it. I bought some plain brown flannel to go with it (on sale too!). My husband's cousin had the cutest blanket. The bottom fabric was wrapped around to the top, making about 2 inches of trim around the top fabric. I have searched all over the internet, and I cannot find how to make a baby blanket with wide trim. All the youtube videos and instructions I have found say to do the trim as thin as possible.

Any ideas?
