Like many of you I kept "go" bags packed with overnight items for whenever my husband or mother had to be admitted to the hospital. And of course a bag with crochet, embroidery or quilting projects.
Now I keep several bags with projects of various complexities so I can grab whichever one if appropriate for where I am going.
And I always keep a bag with a crochet project in the car. It is amazing how much you can do while waiting for a train to pass or someone to come out of the store, etc. It is in a clear bag so I can leave it on the seat of my car and would-be car thieves can see that what is in there and not be tempted to break into my car and steal it. Unless of course, they are a frustrated crafter and have run out of supplies!
