Sewing kit

I found this little sewing kit in my travel drawer. My sister and her husband came over from the USA some time ago and we all went to Paris. We stayed here in St Germain. We all got a 4 day metro ticket. Everyone’s worked except mine. I had to shin over the barrier at night when there was no staff there.
After they had gone home, I found out my sister had hidden metro tickets all over the house. It was ages before I found them all.
