One project down. About a million more to go!
Update: I wanted to add a little more about how I did this before posting it to Threading My Way's pillow page. First, the pillow patterns I found on the web have those nice lines across like the actual emoji, but then the pillow is quite flat. I wanted a fluffier pillow. I ended up drawing a pattern by hand. The downside to an overstuffed version is that you can't get sew in those lines. After sewing that bit of a line at the top it was obvious lines further down would not work.
To fix that first problem on the next pillow (because a half dozen people wanted one after seeing mine), I want to put together a sandwich with a little stuffing for the top piece. That will allow me to put in the lines. Then I will sew on a back panel that can be fully stuffed. I think that should give me both lines and fluff. We shall see!
Now that I think about it, everyone who wanted a pillow was way younger than me. I may be having a Peter Pan moment--or life. Too late to change now.
