I made this placemat for a little boy we know who loves his trains and vehicles. You can't really see it, but I machine-embroidered his name on the bottom right. Never done it before. I used white thread so that, if it wasn't very good, it wouldn't matter too much! It wasn't bad, but not good either. It puckered a lot, especially on the 'o'. Conclusion?

PS I have since discovered that you need a particular foot for your sewing machine to do this, so I'm not too disheartened with my effort using the regular foot!
