My name tag is missing too! Mine has an appliqued sheep in the center, and then a border which I had a lot of quilting pins on, and my name at the bottom.
Our guild gives a "suggested" fabric to use in the pin...but not required, so each person can do whatever they want, using that fabric or not. We have given a piece of counted cross stitch fabric with floss in case people want to embroider their name, again, not required. We haven't had a contest, but that is a fun idea!
Our name tags are required if you want to be eligible to win doorprizes...so, I will have to look hard to see if I can find mine, or make another one before our next meeting in a few weeks.
