As I looked at this, I was reminded of my days in England were I frequently took small projects to work to help pass the time. I did not do it as often here in Oklahoma, because I was far more busy due to my duties as a supervisor. The projects I worked on were generally small enough to fit in the cargo pocket of my uniform without leaving any evidence of something being in that particular pocket. Small nail clippers to trim the threads were my friend, too.
A couple other memories struck me, as well. The first, interestingly enough, was when I was in training. Most of my flight was sitting in a cramped classroom waiting for an instructor to come pull a few of us out at time so we could be evaluated on something. I was sitting on the floor next to a wall. I happened to look over at another female trainee and was astonished to see her knitting. I could only imagine what the instructors would have said if they had seen her. We were required to carry portfolio cases everywhere we went. The cases generally held our training guides and notes. In that trainee's case, it also carried a small ball of yarn, two knitting needles, and whatever small project she was working on.
The second was a friend I had in England. He saw me at the Base Exchange one day looking at the different cross-stitch projects in one of the stores. He asked if I would show him how to do cross-stitch, thinking it might be a decent stress reliever. I agreed, and he selected a simple Celtic cross kit. I got the same one, but I have yet to actually do that particular project. I walked him through the basics, and he completed the project with little trouble, though he added his own touches to it, which I thought was fine. I believe he sent the finished project home to his mother. I left England not long after, and I have doubts that he bought any more kits after I left, which is unfortunate. I have always found cross-stitch to be a good way to keep my hands busy while thinking about whatever may be bothering me at a given point in time.
