I wanted a monogrammed blanket for a co-worker’s grandchild so I made this pattern up as I went. I am sharing the pattern in case anyone else is interested.

I don’t have any other letter charts, but there are lots available online.

When working in rounds, I found the sides to buckle a bit when using the 4dc filet (as though it’s too many stitches for the height of the blanket) but I was able to reshape it quite nicely by blocking the finished blanket. I didn’t take pictures before giving it away though!
