Potholders are an excellent crochet project when you're on the go, because usually 1–2 skeins are enough, and you can easily carry them in your handbag.
Here are a few examples from my shop:

The nostalgic
Milk Can Potholder is crocheted double so you can slip your hand inside. The white dots are crocheted in as bobbles at the same time.

To match it, there is the
Coffee Cup Potholder, which is crocheted using the same technique.

And now, for Easter season, the
Easter Egg Potholder with a tulip pattern is a great choice. Crochet it in soft spring colors; it looks especially charming!
