Some years ago I became the family caregiver going where necessary to take care of whomever needed it. I'm not a nurse, trained as a teacher, but nothing bothers me about dealing with illness or injury when that is needed. One time I was stuck without my hand work-emergencies don't give you any warning!
It was a good lesson to always have something ready, so here is a case that I bought from a cosmetic section of the store. It has lots of divisions and pockets for things. I prepare crazy quilt blocks to put in along with the threads, scissors, and needles in a case. Another handy thing to have is a small sketchbook for thoughts and ideas as well as something to write with.
This needs to be a project without a deadline and only worked on in other places like doctors' offices or the hospital. It's worked well, and I have a stack of completed blocks-a great stress buster.
